YMMV / Mario Party 3

• Accidental Innuendo: Koopa Kid can give out items if you answer his questions "correctly". One of them is "Do you like to tease?"^note  Considering the time this came out and Koopa Kid's characterization, the term "tease" was probably meant in making fun of someone as opposed to the way it's described nowadays.
  • The duel map "Blowhard" is given to Peach, one of the game's two playable girls.
• Awesome Moments: In one cutscene, Daisy, shocked when Bowser sneaks up behind her, ends up sending him flying into orbit by a single slap. While the moment is Played for Laughs, the fact that Daisy was able to single-handily fend off the King of the Koopas and Big Bad of the Mario franchise with just a mere slap is still incredibly badass and it is often cited as why Bowser doesn't kidnap her much.
• Best Boss Ever: The fake Millennium Star is one simply because he's the only Final Boss in the series that isn't Bowser.
• Best Level Ever: Waluigi's Island has many tricks and traps that aren't needlessly unfair, including one in front of Game-Breaker Boo, as well as an island that shifts its spaces.
• Fan Nickname: The "Bitchslap from Hell" for Daisy's big entrance when she shows us how different she is from Peach despite their similar appearances by slapping Bowser into orbit.
• Game-Breaker:
  • As discussed by ZoomZike here, 3's Reverse Mushroom is absolutely busted. It allows you to make anyone, including yourself, have to move backwards the next time they roll. Sounds alright, if a little situational… until you put your mind to it. You can use it to access Boo in multiple turns in a row, or, in some cases, multiple times per turn. But what about split paths? Well, you get to choose your direction, even if the path isn't usually a fork in the road! This allows you to enter Skeleton Gate routes without the Skeleton Key! And the mushroom allows you to ignore board gimmicks, such as Sushi. And this mushroom only costs 5 coins!
  • The Bowser Phone allows players to force any one other player to undergo a Bowser event as if they landed on a Bowser Space. Since many of the outcomes are negative, this can easily be used to attempt to chip off money from other players if they are too close to a star. But that's not the most broken part of it, since it can backfire if the target is given a Bowser Suit, a Bowser Phone, or the event happens to affect the caller as well. The most broken aspect of the Bowser Phone is that the owner can use it on themselves. It's actually possible to manipulate the roulette in this game with practice, so you can force a conveniently-timed Bowser Revolution, Bowser Shuffle, or Reverse Curse to screw everyone else. Alternatively, you can grab an easy 30-50 coins, since Bowser will give out that many if you're broke when you land on a Bowser Space.
  • The Wacky Watch forces the game into starting the last 5 turns when used, and is the only item in the series that directly changes the amount of turns in the game. Got an early lead? The Wacky Watch starts the last 5 turns early so that opponents Can't Catch Up. Falling behind in the last 5 turns? Just use the Wacky Watch on the last turn to extend the game by a few more turns. The only saving grace is that they are only awarded via uncommon random events and is thus extremely rare. Unsurprisingly, it never reappeared in any Mario Party game since.
  • The Switch version comes with the ability to create save states, which allows you to rig the RNG to your favor. It can also be used to get mulligans on minigames and to avoid unfavorable outcomes such as in Chance Time. Best yet, you can exploit this to win in Game Guy's minigames, which will net absurd amounts of coins. Using save states will trivialize Story Mode, and can make earning an S rank a piece of cake.
• Gameplay Derailment: It's actually humanly possible to manipulate Bowser's roulette if you land on a Bowser Space. Not only does this completely neuter Bowser Spaces once you learn the timing, but being able to effectively choose the outcome can be quite handy when several of the options can be outright beneficial to you. For example, you can get a Bowser Revolution to redistribute everyone's coins evenly or earn a Bowser Suit to use later.
• Low-Tier Letdown: For the partners in duel mode, Baby Bowser is the one partner you never want to get from the roulette. His stats are 1 power, 1 stamina, and his salary is 3 coins. Despite his power stat of 1, he does nothing most of the time. His special ability is to transform into Bowser and deal 3 damage, but this rarely happens, making him the only useless partner.
• Memetic Mutation: Sexy Bowser^Explanation Bowser is often seen posed laying on his side in a provocative way whenever you encounter him. The Runaway Guys brought this one to life.
• Older Than They Think: This is the first game where Charles Martinet gives Luigi a "timid" voice in contrast to the deeper voice he used for the rest of the N64 era. Said voice is frequently misattributed to Super Mario Advance or Luigi's Mansion, which were released the same year in North America. It is also the first game to feature Charles' deeper voice for Wario, which is usually miscredited to Mario Kart: Double Dash!!, which released about 2 years later in North America.
• Replacement Scrappy: Tumble and the Millennium Star for Toad. Both replace his roles in the previous games as this game's announcer and the host/purveyor of stars, respectively, leaving him with very little to do. Additionally, since the latter acts as something of a villain in the Story Mode's conclusion, he's not even a genuine Nice Guy mentor that Toad was.
• Scrappy Mechanic: The Game Guy minigames are a major source of frustration for many players. Landing on one of his spaces forces the player to gamble all of their coins on a (usually)^note Technically, there's a little bit of strategy involved with Game Guy's Lucky 7 and to a lesser extent Magic Boxes, since the player can choose to push their luck to increase their winnings if they've already won, at the risk of losing it all (unless, in the case of Lucky 7, the player rolled a 1 on the first die, so there's literally no risk of overshooting it and they basically have a free chance to multiply their coins tenfold instead of the usual double) entirely luck-based minigame, most of which have 50/50 odds at best and incredibly thin odds at worst (we're looking at you, Game Guy's Roulette), in the hopes of walking away with several times more coins than they started with. Unlucky players could lose every coin they have in a heartbeat (costing many of them the entire game), while lucky players who won a game after gambling lots of coins have a very good chance of winning the Coin Star — and in some cases (winning on low-odd Roulette spaces or longshot odds on the smaller Chain Chomp in Game Guy's Sweet Surprise, and landing on the final space in Game Guy's Lucky 7) possibly reaching the coin cap. Notably, unlike Chance Time, Game Guy spaces are frequently placed on the boards' main paths (whereas most Chance Time spaces were placed on Skeleton Key paths, meaning that players typically had to go out of their way to land on one), and even appear in Duel Mode (where losing all of one's coins was effectively a death sentence as it all but ensured that they wouldn't be able to pay their partners' salary at the start of their next turn, leaving them completely defenseless until they found their way back to their Start Space). Even worse? One of the game's rarest items in the Battle Royale Mode let the user force a Game Guy minigame on a player of their choice. Unsurprisingly, this mechanic did not return in future games, and much like the control stick-spinning minigames from 1, are likely the reason why 3 was never released on the Virtual Console (since any depiction of gambling in a video game could easily get it banned in countries that take a dim view of the subject, such as Belgium and South Korea).
• Signature Scene: Daisy's big entrance where she bitchslaps Bowser into orbit and claims it's because he'd gotten in her way.
