The manual for Interplay's PC adaptation of The Fellowship of the Ring had a section explaining that the portrayal of some elements of the setting reflected the source material and might conflict with modern sensibilities.
Natsume has run into this a few times in translating the Harvest Moon games.
The Japanese Harvest Moon DS Cute (2005) had a Romantic Two-Girl Friendship/Gay Option, where your girl could engage in a "Best Friends Ceremony" with some of the other female characters, at which point they'd become essentially the same as a wife. Although relatively mundane for Japan, this would've been considered shocking to certain parties in the US, particularly at the time of release, so the feature was quietly dropped from the US version of the game. Both dropping it and the way Natsume handled dropping it have upset fans, though, and it wasn't helped in retrospect by the fact that, not even a decade later, the feature probably would've survived thanks to America's rapidly changing attitudes toward gay marriage.
There was also Harvest Moon GBC 3, which gave a choice of playing as either a male or female. The male character could get married and have a child and continue playing. The female character's game ended as soon as she married. Also, the love interest for the male character was completely useless until livestock was purchased, which could only be bought after growing a certain amount of grass. The love interest for the female character merely began as incompetent.
In Harvest Moon: Back to Nature For Girl, your game also ended after you became married. Though this was changed in the enhanced port-remake, More Friends of Mineral Town.
If it's historical and has a level of detail beyond personally killing things (effectively, a strategy game), it probably qualifies. Take Rome: Total War: the men in your family line are the most important characters in the game, providing bonuses when they lead armies and run your cities, with stats and intricate trait and retinue systems; the women don't even have stats, they're used for making babies and bringing new men into their family.
Slavery is a particular problem with historical building games. Some use it as a critical game mechanic, others pretend that it didn't happen. In Medieval: Total War, if one is playing as a Muslim faction, it is possible to sell captured soldiers/rebels into slavery (for Christian factions, the option is "execute"). It is also possible to launch Crusades or Jihads against another group.
Each province in Europa Universalis III produces a particular trade good. In Africa, one of the possible trade goods are slaves. The game, however, gives the player no benefit for finding slaves other than the actual direct profit from the trade good... and even then, one prefers to find gold or ivory (Another resource that conjures values dissonance) in Africa. It's possible to abolish the slave trade, at which point all of a player's provinces that "produce" slaves start producing something else; this is usually beneficial, because it gives players another shot at finding gold in their provinces.
Whether you want slaves or not actually depends on economic reasons, just like in actual history. Slave producing provinces give a big bonus to provinces that produce cotton, tobacco, or sugar; and if you abolish the slave trade, you're just as likely to find near-useless millet as you are ivory or gold. Even if you do find ivory or gold, it isn't a huge step up from slaves; and if you own more than a few of the aforementioned provinces that benefit from slaves, you're likely to lose money even if you strike nothing but gold.
Victoria: An Empire Under the Sun and its sequel have gotten a lot of flak over the use of the terms "civilized" and "uncivilized." All the countries in the world are divided into these two categories, with "civilized" countries being able to industrialize much easier and research technology much better. This rather simplistic dichotomy works well for game balance purposes, but still generates controversy. The developers respond that the game, which covers the period of neo-imperialism and the heyday of scientific racism, is by its very scope Eurocentric, and that their detractors are just reacting badly to values dissonance.
Civilization has whales and elephants as exploitable resources your civilization can take advantage of, often as luxury trade goods. For modern, western civs, that might mean tourism, but for most civs in most time periods it really means whaling and hunting for elephants as labor and ivory.
Civilization IV also have the Civic Slavery, which is derided by some players to be inherently evil. Yet in practice is both quite normal given the time period where its most worthwhile in, which pretty much is everything pre-renaissance/pre-industrial depending on your game-plan. And such an strong civic that deliberately not using it might put you back a couple of levels of play.
Similar to the above is the "Heresy" technology from Age of Empires II, which kills any of your units that are converted by an enemy priest. It fits the time, and from a pure gameplay standpoint it's a very beneficial upgrade (you still lose the unit, but your enemy doesn't get it), but many players consider researching it a Moral Event Horizon.
Hideo Kojima's self-confessed fetish for demure, quietly emotional women was never so bad as in Snatcher, where the thirty-two year-old protagonist has a number of sexualized interactions with a demure, quietly emotional fourteen-year-old model. (To give you an idea of the sexualization, she has a birthmark on her inner thigh shaped like a heart, and you actually need to know that (to prove to her that you have access to the Snatch organization files) in order to continue the game. You can also make the protagonist sniff her panties and, at one point, he accidentally bursts in on her naked in the shower.) While side characters complain, it's because the man is technically married, although no side characters comment when another female character asks him out and he accepts. The localization aged her up to eighteen and removed the panty-sniffing and nudity.
Something similar happened in Metal Gear Solid. It's worth remembering that the plot involves an eighteen-year-old who has never had a previous relationship hooking up with a thirty-two-year-old, and that no-one at all thinks this is odd — in fact, the other characters actively encourage it and point to her youth as a reason why she's perfect for him. It gets worse when you remember that Meryl was originally going to be thirteen (modeled after Natalie Portman's character in The Professional/Leon), and was only aged up to an adult because the character designer had trouble imagining a thirteen-year-old handling a Desert Eagle like in the script.
This is itself an example of Values Dissonance — 16 is the Age of Consent in most of the developed world, including most states in the US. People in the US tend to think of treating 16-year-olds as sexually available adults creepy because 18 is the age of consent in California, which produces much of the US's entertainment and exports its ideas about the appropriate age of consent and when someone can be considered a mature adult to the rest of the country.
The age of consent in Japan is actually 13 (with some restrictions).
This is also slightly mitigated by the fact that Paz is not actually 16 years old.
The European version of Platinum removed the slot machines because PEGI has gotten harsher on gambling references. Moral Guardians elsewhere complained too, and in HeartGold and SoulSilver, the slot machines have been removed outside of Japan (even in North America, which did have slot machines in Platinum) and every game (including remakes) released afterward lacks them even in Japan (this is lampshaded in Omega Ruby and Alpha Sapphire).
The Pokémon games also give a meta example: The idea of splitting the content between two games and requiring players to trade for version-exclusive content is often viewed very differently by different audiences. The Japanese players see it as a Socialization Bonus. A lot of western players see it as a money-grab that forces them to buy the same game twice for 100% completion.
Some believe that this is why the starters are generally predominantly male. In Japan, gifts are Serious Business, and female Pokémon are considered more valuable than male Pokémon due to their role in the breeding mechanics (females determine what type of Pokémon is born, males determine the child's move set, the latter prior to Gen. VI). Thus, since each Gen's starter is a gift to you from the region's Pokemon Professor, the male to female ratio for Starters is heavily on the male side to discourage trading it.
The Pokémon series usually treats children leaving the house at a preteen age to become Trainers as perfectly natural. In some other countries, as has been addressed throughout the page, an eleven-year-old leaving the neighbourhood unsupervised can cause mass panic, much less walking around the country. Pokémon Black and White addresses this, as it's set in a counterpart region to New York City and nearby parts of New Jersey rather than somewhere in Japan, so the American (particularly urban American) aversion to Free-Range Children has to be looked at. The protagonists are ambiguously between fourteen and seventeen this go around, rather than explicitly eleven (RGBY) or ambiguously ten-to-thirteen (other games in the series). Even then, Bianca's father is very apprehensive about letting her go off by herself and appears to try and bring her home when she reaches Nimbasa City. And in Pokémon X and Y, which is set in a counterpart region to France, the protagonist's age is even more ambiguous as it's possible to make them look older or younger simply by changing their hairstyles.
The entire concept of Pokémon to certain animal-rights advocates seems like the idea of capturing monsters and forcing them to fight, seeming suspiciously similar to bloodsports like cockfighting, and trapping the Pokemon in Poké Balls has been compared to caging circus elephants. PETA even released various... parody games (for lack of a better word) in which the Pokemon fight their abusive trainer, or similar. (For whatever reason, they waited until long after the series became an established Nintendo franchise to do so; at least the Mario one referred specifically to a then-recent release.) Nintendo did fire back on these, however, with threats of legal action. Originally it was actually intended to represent a game that captured the childhood passion that the original Game Freak creator Satoshi Tajiri had for collecting bugs and letting them fight against each other. However, as the company switched from CEO to CEO it has become established that the Pokemon in-universe are sentient, and willing to fight and compete with each other. This isn't unlike several real-life animals (if anything, Pokémon battles are less dangerous than that).
The Disgaea series is consistently rated A in Japan, the equivalent of E or a low-end E10+, and is marketed accordingly. In America and Europe, the games are rated T and 12+ respectively, and aimed at teenagers and adults, as the games have a lot of fanservice designs and shots, particularly after a battle is completed. The English translations also tend to have a moderate amount of profanity.
Shirou Emiya earned a large amount of fan hatred for his seeming Stay in the Kitchen attitude towards Saber's fighting in the Grail War. Some argue he's actually a subversion, just mortally afraid of Saber dying - although heroic spirits don't actually 'die' (and painfully aware that he's not qualified to fight alone) and initially doesn't understand why, settling on this as a random excuse (although he says Kiritsugu taught him 'girls should be protected'). Notably, he doesn't act this way towards any other woman, even Saber herself in the non-Fate routes, and the very idea is even mocked on occasion. This doesn't dismiss his bizarre approval of Ayako's attempted molestation for 'teaching her femininity' (though even the other characters in-story were angry with Shirou over that remark). However, this along with Stay in the Kitchen, fades from the later arcs, and in another arc where Ayako is attacked by Rider but Shinji spreads rumors implying she was raped, he is horrified.
In the original Japanese version, Shiro, Rin, and Sakura are around fifteen or sixteen, being in their second year of high school, and Saber's apparent age is stated to be one year younger in an interview with Nasu. While this is over the Japanese age of consent, the American version comes with a disclaimer stating that all the characters are over the age of 18 due to the high amount of sexual content.
Mara's presence alone should be enough to force an M rating on any MegaTen game it's in. The few US-released games in the franchise that don't have a T rating are the same games that don't feature him. A prime example would be comparing Persona 4: Arena Ultimax to Persona Q. Ultimax is a fighting game that features teenagers beating up each other with swords, knives ect. and doesn't have Mara. It's rated T. While Q has a RPG elements of defeating Shadows and even has a cute artstyle...and has Mara. It's rated M. M for Mara indeed.
There's even a bit of Values Dissonance between English speaking countries on the series, since America is the only country that rates the Persona series as high as M (17+). There, "sexualized imagary" (Mara and some female Personas having exposed breasts) is enough to warrent an M rating, whereas other countries don't consider that nearly as harsh, since there's no actual sexual acts depicted in the series. Looking at the ESRB page for Persona4 also shows that a major factor in its M rating was the "King's Game" scene, where the teenaged protagonists go to a bar and start acting drunk and playing "drinking games" despite the game making very clear that their drinks are non-alcaholic (the bar has never served alcohol in years). This is probably due to America's legal drinking age being much higher than most other countries.
Shenmue II has a barmaid in the British Colony of Hong-Kong thank Ryo for being so honest about being too young to buy alcohol at age 18. For the record, legal age for buying alcohol in Britain (and Hong Kong) is 18, but it's 20 in Japan and 21 in the US.
Sort of noticeable in the Metroid series of games: In the Japanese-made 2D games, Samus is a somewhat understated character, implied to not be terribly well-known outside of people who need to know who she is (typically, the Federation and some of the Pirates that she has history with). In the American-made 3D games, Samus is well-known by nearly everyone, played up like some sort of celebrity or war goddess, universally feared by the Pirates and well-respected by even the newest recruits in the Federation; in other words, a more Hollywood-esque portrayal of a heroine of her stature. Incidentally, the Japanese 2D games are also the ones to show Samus scantily clad in her "reveal", even in Zero Mission, the first 2D game to show her in her Zero Suit (which appear in some of the endings, but she's wearing less in others). It was the Americans who first made an attempt to cover her up, with Prime never showing less than her without her helmet, and Prime 2 featuring her slinky but functional-looking Zero Suit. Prime 3 goes back to a simple helmet removal.
Of course, this has led to a large quantity of Americans Hate Tingle with the latest release in the series, Metroid: Other M; some of which being the various materials that were published to establish her emotions. For instance, the Japanese viewing "Bounty Hunter" as just a cool title rather than a badass anti-hero and/or amoral law enforcer, with a proposal in Prime 3 by Retro for side quest bounties being denied by Nintendo as something a good person like Samus would never do.
This trope is in full effect in Other M with Samus's relation with Adam.note And arguably the entire game. As mentioned above, in Japan Samus is less a bounty hunter and more like a Private Military Contractor who still technically works for the Federation military just on a less formal basis. As the story was written with the Japanese fanbase in mind, they consider Adam's assertions of his rank over Samus to be normal procedure. In America, Adam is seen as a psychotically abusive controller who has mentally conditioned Samus to obey his commands even after Samus has stopped officially working for him.
One need only look at Other M's reception among fans and critics in the West and in Japan for a good example of Values Dissonance. While Critical Dissonance is in full effect on both sides of the pond, Western fans utterly despise the game with very few exceptions (due to the mentioned Samus-Adam "relationship", and if not that then Samus's encounter with Ridley) while Japanese fans are more mixed, leaning negative. Its major criticisms are roughly the same in both regions, interestingly enough.
In the Japanese release of EarthBound (Mother 2), in the land of Magicant, which exists only in Ness's mind, the protagonist is naked (a Japanese symbol of purity), while in the US he appears in his pajamas as he did at the beginning of the game in all versions, as nudity—especially child nudity—is considered extremely sexual there.
While received favorably outside of Japan and generally seen as a fun and heartwarming game with tons of Video-Game Caring Potential, Valkyria Chronicles has a strongly Japanese ideal of unity and has a tendency to kill anyone with a unique character design who either doesn't wear some type of uniform, or betrays the one they have. It leads to some Family Unfriendly Aesops when it comes to the titular Valkyria, who disavows her superpowers essentially because they make her stand out too much.
That...might explain why Valkyria Chronicles III completely went the other direction when it comes to values (except Camaraderie, that's inviolable). Your characters are society's refuse, they constantly go against their superiors' orders (for better or for worse), at some point they have to fight and kill their own countrymen, and their Valkyria, Riela, is not trying to do anything to change people's perception of her as a "freak". VC3 thrashes the usual Japanese values out of the window and then tosses live grenades on them just to make sure.
Rule of Rose was subject to this trope in many parts of Europe where the publishers were pressured to pulling it out of the shelves. All because it depicted children as something other than innocent little angels, capable of extreme cruelty and spite, and possessing early signs of developing sexuality — even though nothing unwholesome happens with preteen children in that area, and the sexual abuse of a sixteen-year old girl is treated with all the horror it deserves.
The Nancy Drew game Shadow at Water's Edge plays with this trope, as it is set in Japan. Part of Miwako's resentment towards Yumi, apart from sibling rivalry, is that she left the Ryokan to start her own career making bento instead of staying to run the hotel as expected of her. According to Miwako, this makes Yumi "selfish". This logic only makes sense if you understand that in Japan, independence is frowned on and that you're supposed to do what's expected of you. However, it is also revealed later on that the girls' mother actually wanted them to lead their own lives and not take care of the Ryokan unless they wanted to do it, proving that the general attitude towards an issue does not necessarily hold up for everyone.
Godot, a character in the third Ace Attorney game, is viewed by western audiences as sexist and patronizing towards women: he refuses to take Franziska seriously and tends to refer to her by condescending pet names, not to mention his insistence that Mia needed to be protected, if not by him then by Phoenix. While it is still presented as a character flaw in the Japanese version (given that his guilt over his failure and resentment toward Phoenix led him to make a plan to protect Mia's sister Maya that results in him killing their mother), it's not presented as a serious flaw; as a result, he's pretty much universally beloved in Japan (although he is still much-loved in western audiences as well).
Godot in general tends to be a source of Draco in Leather Pants, from both Western and Eastern fans, who see his 'women must be protected' thing as romantic (towards Mia) rather than sexist.
Well, if he knew about Franziska's tendency to whip and slap everyone around her to get her way, Godot may have been playing more on her immaturity and young age than her gender. Which goes with him calling her things like "filly". There is no retort for the 'women must be protected' thing, however.
This trope may also account for why Dahlia Hawthorne repeatedly makes mean-spirited jabs at Mia's age, calling her "Madame Fey" and a "spinster". At the time of her death, Mia was twenty-seven and very attractive, leading these insults to seem pretty out-there to western players. In Japanese culture though, a woman tends to be considered past her prime when they're twenty-five (though this is becoming a less-common view).
Japan insisted on partial removal of nukes from Fallout 3 before it would permit release in the country. Specifically, the nuclear bomb in Megaton could originally be either permanently defused (good option) or rigged to blow up the entire settlement (evil). The Japanese version removes the latter option and also renames the "Fat Man" nuclear grenade catapult to "Nuka launcher". Strangely enough, the weight-reducing modification kit for the weapon apparently retained the name "Little Boy".
This trope is part of the reason American Kirby Is Hardcore exists. While video games make cute characters and box art a common selling point in Japan, in America it is relatively a niche market outside children or casual gamers. Attempts to move towards the happy box art of most Japanese games is far outweighed by the amount of box art that turns them into sword-wielding warriors or have them wear scowls on par with Jean-Claude Van Damme. Case in point—the Starfy series was a big hit in its native Japan, but despite a fun and unique gameplay style, the cutesy appearance of the title character caused the series to be a commercial failure in America and no games have been released since in any country.
Quite a few games with an ESRB rating back in the 90s when released today have had a change. For instance, a few K-A (Ages 6+) games get slapped with the newer E10+ (Ages 10+) or even T (ages 13+). The new ratings come with extensive lists of possibly objectionable content listed on the website as well, which allows consumers to make a more informed decision based on their own values and avert this trope. Sonic Adventure 2, when released for Dreamcast and Gamecube back in '01, got an E for Everyone rating, but when it was re-released for XBLA, PSN, and Steam in 2012, it got bumped up to E10+, because its content is now considered too dark and mature for an E-rated game.
The opposite can happen too: In 1984, Germany banned River Raid for its violent content; in 2002, the ban was lifted, and it was rated free for all ages. In America, the Streets of Rage series usually got MA-13 ratings (Sega's equivalent to the T rating) because they were considered very violent for their time, but with modern-day re-releases, they are now rated E10+ because they're not as violent as games you'd see today.
Left 4 Dead 2 is filled to the brim with zombies that can be blown apart to pieces and have their blood and guts spill all over the place. Most places in the world are used to this type of violence in media, but Australia and Germany are heavily against such violence and consider this type of content too extreme for minors. The German and Australian versions of the game are heavily censored by disabling dismemberment and zombies immediately vanish upon death. The fire effects on zombies are also disabled, which can actually make the game harder if you can't tell whether or not you set zombies on fire.
The censored versions of the game also removed the riot infected (zombies in body armor) because Germany and Australia heavily frown upon violence against authority figures. Some time later, Valve was allowed to put the removed zombie back in the game after they removed the "Security" logo on the chest.
Australia's game classification system in general can be a case of this trope for other countries, as several games are rated higher or lower there than averywhere else. It seems that sex and violence are really the only things that can push a game into the two highest categories (MA 15+ and R18+), while countries like America can have games rated M due simply to mature themes (the MegaTen series being a prime example). Australia also views cartoon violence as less "harsh" than realistic violence, hence why games like Super Smash Bros., Ratchet & Clank, and Team Fortress 2 get lower ratings there than America. Meanwhile Atelier Totori: The Adventurer of Arland, rated T by the ESRB and 12 by PEGI, was classified R18+ in Australia simply for "references to sexual violence", EarthBound is slapped with an M (13+) for crude humor and "sexual references", and The Legend of Zelda: Skyward Sword got a 15+ rating over there, but an E10+ rating in America and 12+ in Europe.
This even extends to Europe as well. In America, Bayonetta and Lollipop Chainsaw both received the Mature 17+ rating, whereas Europe gave both of them the 18+ rating due to having lots of gore and sexual content/dialogue. Also in Europe, Metal Gear Solid 3 received an 18+ rating (it got the Mature 17+ rating in America) all because of the torture sequence.
Blizzard repeatedly had trouble distributing World of Warcraft in China because Chinese culture considers desecration of the dead, and any depiction of bones or mutilated corpses, obscene. Among the changes that had to be made were removing exposed bones from undead models, replacing the skeletons left by player deaths with headstones, and changing the graphics for decapitated heads with bags implied to contain them. Lord Marrowgar, a large monster that's made up of bones◊, had to get an entirely new model◊ in the process (and presumably, so did his Palette Swap, Earthrager Ptah). None of those would make a Westerner bat an eye.
Another problem was that China worried about game addiction a lot more than the western markets, forcing Blizzard and other companies to implement stronger Anti-Poop Socking measures.
A noticeable aversion was the Mists of Pandaria expansion. Despite showing China's beloved national animal, the panda, in scenes of brutal fighting, explicit torture, and less-than-upstanding social situations, China was too flattered by how incredibly badass they were and how well they captured the most endearing parts of their scenery and culture. This meant that Pandaria was the first expansion that didn't have be Bowdlerized and got a truly global release. As an aside, the original reason Pandaren hadn't appeared in the game earlier? China was angry that the Pandaren brewmaster in Warcraft 3 had a Japanese style instead of a Chinese style, that Blizzard got it right in Pandaria may have been another contributing factor.
Pretty much a given for any Romance Game or Dating Sim. Cultural differences in gender roles have a lot to do with that.
Doom is still a pretty bloody game, but it's very hard to imagine it attracting the controversy now that it did back in the day after the release of other games that top it in the gorn department several times over (God of War being a shining example).
Wolfenstein and Mortal Kombat were also shocking, Mortal Kombat because the entire point of the game is to kill people for sport (although the blood just looks like thick tomato juice) and Wolfenstein because at that time it was unprecedented for a video game to contain bloodshed at all (even though the graphics on that game were so primitive that the blood looked more like red confetti than anything else).
Kunio Tachi No Banka: Sabu shot Misako, Kyoko, and Ken during different parts of the game. While it's already considered to be a Moral Event Horizon, the Japanese gun laws prohibits most kinds of firearms to the point that even some Yakuza refuse to hold one with the penalties being high (firing irresponsibly ranges from three years to life in prison). It also means that Sabu lost his honor after those acts.
Dead Rising 2 has a lengthy plot about how Phenotrans is keeping life-saving medicine from the public due to the cost exceeding the benefits from giving it. This is just plain strange to countries where medicine is a government provided service.
In Japanese media, crossdressers are sometimes viewed as transsexual by Western audiences, with Naoto Shirogane from Persona 4 and Chihiro Fujisaki from Dangan Ronpa being the most prominent examples of this issue, as a handful of Western fans insist that they are transsexual despite canon saying otherwise. This is due to misunderstanding their problems in regards to Japanese culture; in Japan, it is extremely important for a person to fit a certain criteria of what it means to be female and what it means to be male. If they don't meet enough of that criteria or act in a way that is against it, they are shamed for it or not taken seriously. Naoto was insecure about her femininity because she wanted to pursue a career in a male-dominated field but knew they would dismiss her skills if they knew she was a girl. So she cross dressed in order to make sure that didn't happen. Chihiro was constantly bullied because he was too frail and shy to be considered a real boy by Japanese standards, and started cross dressing as a means of escape since his personality was seen more proper for a female, not because he identified as such. Both are examples of individuals who couldn't live up to the gender standards of Japan and had to find a way to conform to it instead.
A similar problem arose with Kanji from the same game as Naoto. To a lot of Western players, his shadow and problem is often seen as his being Armoured Closet Gay. According to Word of God, Kanji's sexuality is supposed to remain ambiguous to each player, though his actual problem is stated to having to do with his hobbies: drawing, crafting things with his own hands, which includes knitting things. It's the same issue as with Naoto, Kanji is aware that his hobbies are not those of 'a man' and he hence would not fit into the idea of what a man is. Even with Kanji admitting that he wants someone to accept him with his un-manly hobbies, a lot of Western players remain on the whole gay idea.
Unfortunately, that led to an even bigger problem for Yosuke, a lot of things he said throughout the game to tease Kanji about his issues ended up making him sound homophobic to Western Audiences. The Japanese aren't that big on the sexuality subject so in many of their anime and games, they have comic relief characters whose main joke is that they may be gay.
One theory that has been made to explain why JRPG's are popular in Japan but not in the West is the fact that JRPG's require a lot of level grinding. Japanese gamers are perceived as being more patient than Western gamers and perceive the idea of level grinding in order to get some ultimate reward in the end. In the West most people do neither have that kind of patience nor the wanting for a reward, which is the reason why many Western gamers get frustrated with those games and give up on ever trying one, which results in low sales. This may be the same reason Monster Hunter is a best-selling series in Japan, but is a Cult Classic at best in the United States.
Clayfighter 63 1/3 has one fighter named Kung Pow, who looks like a caricature of the Asian stereotype, but is played straight. Aside from the typical squinty eyes, Kung Pow uses woks for one of his attacks, has typical kung fu acrobatics, and pulls out a Chinese carton of food when he wins and asks if it's to stay or to go. While no one would have batted an eye to the stereotype in 1997 when the game was released, looking back on it in today's time makes the whole character be seen as terribly racist or the developers simply not thinking things through when they designed the character.
Then again, with Wooden Sensey being released and no-one daring to suggest more than that it "verges on" racism, maybe we're not so far past that after all.
The Tower of Druaga. The game boasts a 60-dungeon floor with many treaures to uncover, many of which are required or else the game becomes much harder at best and Unwinnable by Design at worst. The treasures often have absolutely obtuse requirements for revealing them, and just to make matters worse, some treasures actually hinder the player despite their obscure requirements. The game was a hit in its native country of Japan, but failed to find an audience in Western territories, especially the US. Part of the reason it succeeded in Japan is that Japanese gaming communities tend to be more communal; players at arcades will often exchange strategies to help benefit each other, and some arcades will have guestbooks for customers to write in, often to discuss these strategies. By watching others play, one could learn how to unlock each floor's respective treasure without having to commit a lot of Trial-and-Error Gameplay; in the 80's, well before the age of the Internet as an affordable service, discussing with and watching other players at the arcade was the only way to finish the game if you didn't subscribe to magazines or the like. The idea of arcades being places where players socialize is somewhat lost on Westerners, save for scattered pockets of Fighting Game players and Rhythm Game players, and on top of that, there is the commonly-Western idea that using guides and others' playthroughs to facilitate one's own progress in a video game is a sign of weakness.
7 Sins, which is probably the closest thing in Europe and Brazil to an eroge, features an interesting set of this when it comes to erotic content in gaming (read: softcore sex scenes). PEGI (which covers Western Europe) and USK (which covers Germany) gave it a 16+ rating while the BBFC (which covers the United Kingdom) gave it an 18+ rating. It seems that the UK has quite different ideas from the rest of Europe when sexual expression is concerned.
Similarly, America's ESRB is much harsher on sexual content than most other countries, and many games that get M ratings for sexual content in America get lower ratings overseas (such as Akiba's Trip, which is rated the equivalent of T in Australia). "Partial Nudity", which even extends to exposed breasts on monster enemies not intended as sexual, is grounds for an automatic M rating in the ESRB's system, while other countries allow it in lower ratings and only give high ratings for full-frountal, explicitly sexual nudity. And the gap between the ESRB's M and AO ratings is only sexual content in most cases, leading to Grand Theft Auto: San Andreas getting pulled from shelves and re-rated due to the "Hot Coffee" mod (there was little fanfare in Europe since the game was already rated 18+ for violence anyway). Skimpy outfits on characters is sometimes enough for an ESRB M rating, which often results in outfits being censored in US releases (for example, Tharja's swimsuit scene in Fire Emblem Awakening's DLC was censored in the US version, but not in the European version).
50 Cent once mentioned he played the games he starred in with his kid, saying that violence wasn't an issue as long as he was around to explain it but that he would turn the sound off because of the swearwords. Some people in Germany, where people no longer give a shit about swearing but violence remains the Moral Guardians' Berserk Button, burst into laughter at his priorities.
In the United States, a common practice for queueing up is to put down some sort of object to symbolize your position in the line, often a coin or a card; once your marker is at the front of the line, you drop your credit in and play. In fact, for a long time, arcades could purchase "Competitor" coin racks for players to put their queue-marker coins on. Once your credit is up, it's time to hand your turn to the next player and move your marker to the end of the line if you intend to play again; playing another credit when someone else is waiting is seen as selfishly hogging the machine and is a Fandom Berserk Button.
In the Philippines, you drop your credit(s) in to indicate lining up, and however many credits are before you indicates when your turn comes up. Most players will often stack multiple credits; while some players will get irked at the practice, it's widely accepted, if grudgingly.
Killer7 has high ratings in most of the world (in the US it got an M and in Europe it got an 18+), but in Japan it was so controversial that it has gotten a Z rating (which is the Japanese version of a US AO rating) after some of its scenes were censored. This is one of the few cases where a Japanese game is less offensive to foreigners than it is to Japanese themselves.
The Western release of Fire Emblem Fates had its skinship feature removed, with Nintendo openly stating the change was due to values dissonance between what is considered acceptable in Japan vs. what is considered acceptable in North America. It didn't stop many fans from protesting the removal and other changes as unnecessary censorship.
Additionally, the fact that Fates features a bisexual protagonist with two gay options is quite progressive... in Japan, which is actually not as LGBT friendly as some people like to believe. Meanwhile, Forrest is mocked in the west for his appearance, despite that that isn't seen as too controversial in Japan.
The Longest Journey was made in 1999 and 2000, and it was rated "M". Playing it today, you would actually be wondering why it is rated "M", as any violence, gore, and innuendo is what the ESRB actually allows in a game rated "T" today.
Final Fantasy VI is remarked upon for its strong female characters, who still stand up as such today. Unfortunately, it also has multiple heroic male characters who are sexually violent or possessive towards women, with this being played as a charming mild flaw (child-flirting Edgar, celebrity stalker/kidnapper Setzer) or tragic but romantic (Locke, who keeps his dead ex-girlfriend's corpse preserved in his basement). This was accepted as a normal trope in pulpy fantasy fiction in Japan in 1994, and at the time signalled a Darker and Edgier, Hotter and Sexier tone that averted the Politically Correct History of previous Final Fantasy settings. Nowadays it comes across as being quite awful. Even Squaresoft felt embarrassed about it, to the point where an intentional goal for Final Fantasy VII was to make it less sexist.
