These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Blanka. He was very ferocious in his first appearance. Nowadays, he scratches his ass, growls like a monkey and whines about his mama. He also become a Tier-Induced Scrappy thanks to his ability to tick throw with any attack. Chomp Chomp! Oh, and he's the Joke Character's sidekick. A Hypercompetent Sidekick, but still. If you look at it carefully, Blanka is (kind of) to Dan as Brain is to Inspector Gadget, with Sakura filling the Penny role.
Akuma, or at least, how some people feel about nerfing him.
As can be partially seen in the linked-to Shoryuken Wiki thread, many older players — as in, those who've been playing SF ever since one of the II games — have many issues with IV, most of which are very technical. Whereas newer players say that they're old fuddy-duddies who should go back to where they came from. What your stance on the game is, is ultimately up to you...
A trailer for the arcade edition of Super Street Fighter IV ends with the revelation of two other characters in addition to the well-received Yun and Yang: Evil Ryu and yet another version of Akuma named "Oni". Counting all alternative/full power forms present, this gives us a grand total of twelveShotos. And boom goes the dynamite.
It has died down since then, though, as people have gotten to play Oni and though he shares some of Akuma's moves, he's no clone.
Although a different backdraft has popped up over certain fans preferring to rather see other characters that have disappeared from the series since the time ofAlpha and III (Karin, Rolento, R. Mika, and Alex are frequent mentions) as opposed to "What If?" versions of Ryu and Akuma who really don't do anything to move the story since they're non-plot entities judging by III.
More proof that history is perpetually doomed to repeat itself: the announcement of Ultra Street Fighter IV—the fifth SFIV installment if one excludes SSFIV: 3D Edition and counts the Arcade Edition Ver. 2012 patch—has reopened old wounds. Another copypasta cashgrab on Capcom's part or a chance to play as more fan-faves without being bogged down by the various problems that plagued Street Fighter X Tekken's production? An accepted (and expected) tweak to the SFIV engine or time and resources that could've been put to better use for an actual Street Fighter V or, in the eyes of many, a continuation of any other Capcom fighting game series not named Street Fighter? The continued absence of characters fans have been clamoring for since vanilla SFIV like Karin, Alex, R. Mika, Q, etc. (read: "nearly anyone from Alpha, III, or the EX series that has yet to resurface in IV") and expectation of the usual from Capcom when it comes to DLC isn't helping matters in the slightest. What possibly lessens some of the base-breaking is that many players had been asking for the four characters from Cross Tekken to be ported over to Street Fighter IV.
Ironically enough, the four characters ported from Street Fighter X Tekkenthemselves added to the Broken Base. Are they great and interesting characters that should have a second chance in Street Fighter IV considering the hate for SFxT and whose presence is justified due to their popularity or are they just lazy ports whose novelty has gone and whose spots should have been given to a character that hasn't been seen in a long time?
The storyline in this game and how it affected the series' storyline as a whole. Some liked how IV gave a number of recurring characters more screentime than Street Fighter III did. Others blame this game for causing a lot more Retcons in the series and making the series' storyline a bit more of a jumbled mess.
Character Tiers: It has them, like any fighting game, but IV is notable for having one of the smallest "spreads" in the history of the series (or any fighting game, really). The worst characters aren't really that much worse than the best ones, and none of them are really considered garbage by the general community. Individual opinion is another story, of course...
Creator's Pet: Rufus seems to be turning into one of these after he made it into Street Fighter X Tekken as Zangief's partner, much to the dismay of R. Mika fans everywhere.
Complete Monster: M. Bison is pretty much the living embodiment of evil, since that's the gist of his powers.
If her OVA is any indication, Juri's only soft spot isyoung children; when her Feng Shui Engine goes haywire and she unwittingly blows up an amusement park during a test drive, the only survivor is a crying boy, whom Juri deliberately avoids and ignores while standing in silence. This is likely rooted in her own childhood trauma.
Ear Worm: Thanks to it being in both the intro and the main menu for the game, "The Next Door - Indestructible," the theme song of SFIV. Its J-pop beat quickly got into a lot of players' heads. In fact, Gamepro even deducted a point in its review of Super for not including the song.
Fan Dumb: Apparently, a black British gentleman is still something so foreign to some people that lengthy debates about Dudley's ethnicity rage to this day. His overtly Caucasian features don't particularly help matters...
Zangief. His special grabs now have high priority. To make matters worse, the directional input for the special grabs has become insanely easier. It now only requires a half-circle motion with a diagonal up-forward or up-backward direction, followed by a punch or kick button. Also his EX Banishing Flat can beat pretty much every move in the game due to its abnormal invincibility. And his Siberian Blizzard Ultra seems to be heading this way, given the invincibility frames while midair and its ability to out-prioritize almost everything.
Ryu in vanilla IV. Not only did his combos do more damage overall, but he had a Super trap (throw fireballs, if they jump wrong, take 33% of their health for free) and trade Ultra (mash a Shoryuken on your wakeup, and if they were jumping at you, free Ultra for ~40% with no Super-bar use).
There's a reason Sagat is god tier in vanilla IV: the damage and utility on his moves, in particular his Tiger Uppercut, are so above the other characters it's ridiculous.
In Super (before AE), the cast was utterly dominated by 4 characters: Guile, Chun-Li, Bison, and Honda. All of them were charge characters who could completely control the space of the battlefield and punish an opponent's mistakes harshly. Guile is, well, Guile. Chun-Li can both turtle and punish very effectively with her excellent reach and priorities on her moves. Honda can use his light Headbutt for practically any situation. Bison can turtle when he has the life lead, but when he goes on the attack, which is 100% of the time, he dishes out serious damage, both mentally and physically, with his crazy yet simple mixup and his powerful yet simplistic combos. And his Scissor Kicks are just that good.
Finally, in AE, we have the twins, Yun and Yang. While they share a spot with Fei Long, the twins utterly dominate the rest of the characters. Why? Because both of them are insanely fast, have infinitely better dive kick mixup than Rufus, can turtle AND rushdown at the same time, and with their supers have the ability to perform utterly incredible combos that will instantly result in a dizzy and a reset. These special combos can range from within the 20 hit range to as much as 96 hits. Their one and only weakness is Zangief, so unless you play as Gief you have 0 chance of winning.
SSFIV: 3D Edition allows mapping of any special to a button or the touch screen. This eliminates all charges for any charged attack, effectively making the characters who were balanced by this charge time horribly broken. It also makes it very easy to perform moves that had their tremendous power balanced by the fact that they were normally very difficult to pull off.
In AE 2012, we have the "Vortex" characters: Akuma, Cammy, Gen, and Ibuki. All have tons of ways of getting a knockdown, which leads to either a 50-50 mix-up (will they hit you left or right), which leads to another knockdown, which leads to death. And that's when they're not straight-up hitting you with actual UNBLOCKABLES...
Hilarious in Hindsight: In the Street FighterAmerican cartoon there was an episode in which Akuma paid his brother Gouken a visit, attacking him with the Raging Demon; however, Gouken was only injured, and had to rest for a while. Fans have complained about how the show took an overly Lighter and Softer take on that scene by having Gouken injured instead of killed off because it was a kids show. And that scene was inaccurate to the game's storyline... until Gouken was announced as playable in IV.
Juri is both Memetic Molester and Memetic Sex Goddess, and is probably the closest case to being canon. Her win quotes make it pretty clear that a win for her is much more than merely beating your face in. Just check out all of her Rival Battles; she's openly hitting on the likes of Chun-Li, Cammy, and M. Bison.
Akuma's new Ultra in Super IV, Demon Armageddon, has him kick the opponent in the air, then proceed to do a super version of his Hurricane Kick that makes a tornado appear from under him in order to propel him high enough to give the opponent a massive kick to the chest that goes through them. The concept seems awesome, but the presentation is downright silly. Many times over this move has been compared to Beyblade and Looney Tunes.
The PC version, in addition to running like greased lightning, also offers a plethora of selectable graphics mods to choose from to spice up the game, not to mention the gratuitous amounts of modded content available.
May be the case with SSFIV: 3D Edition; it is a complete port of the home console version (with downgraded graphics that the 3DS can handle), but also has new features that take advantage of the 3DS's Tag Mode and Wi-Fi.
Rescued from the Scrappy Heap: There is one Seth that is generally liked by the fans. Korean gamer Poongko's Seth. Not only does he highlight just how damn dangerous Seth can be, but Poongko also made Seth more entertaining after flawlessly dismantling Daigo "The Beast" Umehara's Yun (one of the most broken characters at the time) at the EVO 2011 Street Fighter Finals. Here is the entire match.
"Everybody hates Seth, that's why he's back as the end boss in SSFIV. I want to torture people with him!" and admits "Seth will remain a target of universal hate."
El Fuerte. It comes as no surprise at all that most of the initial SFIV roster sans Gouken (and C. Viper, but for a very different reason) has been announced in Street Fighter X Tekken except for the hated luchador himself. The same is also true for Seth.
Tear Jerker: T. Hawk's ending in Super SFIV. It turns into an arguable CMOH at the end, though.
Dudley's new English voice actor for Super IV has caused a massive uproar amongst fans, despite the character finally returning to the lineup. It would seem that the popularity of Francis Diakowsky, who voiced Dudley in 3rd Strike, is just as big as the character himself. Not to mention that, while he still retains his rose taunt from 3rd Strike, many were pissed to know that the rose doesn't do any damage in SSFIV. At all. Not even that one point of damage needed to finish an opponentwith style.
However, his new voice does make him sound like Westley.
Almost any change to a character's stats in Super Street Fighter IV from buffs to nerfs, someone, somewhere, will complain real hard about the changes.
Chun-Li's Super IV version barely avoids this. While she's still top tier, there are other characters just as good as (and more hated than) her.
Yun in Super Street Fighter IV: Arcade Edition falls squarely into this status. His godly pressure and general ease of use has made him overused and overpowered to the point where Japanese players will supposedly audibly groan when he's picked.
Ugly Cute: Blanka, debatably, going hand-in-hand with the aforementioned character progression.
We Want Our Jerk Back: Dudley's brand new nice-guy persona, and lack of gentlemanly snark has not been well-received by all fans, with some feeling that leaving out the snark has been detrimental to his character, making him more bland and less badass. This personality alteration has also rendered his classic "Gutter trash!" insult as incongruent and seemingly out of character with his new persona as a constructive, amiable sort of chap.
