Super Mario Bros. 3/YMMV


 * Anticlimax Boss: For the final boss, Bowser isn't really all that big of a threat. You basically dodge his fireballs, and force him to ground pound through the room's floor until he falls through and dies. His fireballs are easy to dodge, and Bowser himself isn't exactly that hard to avoid either.
 * Best Level Ever: World 5-3. Goomba's Kuribo's Shoe. An entire generation of gamers can bond over how awesome that level was.
 * Although not quite as awesome as 5-3, 4-6 contains doors that change the size of the enemies between the giant size typical of world 4 and the standard sizes found elsewhere -- kind of a 2D precursor to Tiny Huge Island from Super Mario 64.
 * The treasure ship, which shows up if your score and coins meet a certain criterion. When you go to it, it's kind of like a Doom Ship, except covered in hundreds of coins. It is glorious.
 * Demonic Spiders: Boss Bass, who can be found hanging around most of the stages in World 3, and has an annoying habit of swallowing Mario whole irrespective of what power-up you're using, instantly costing you a life.
 * The singular fire breathing Nipper in 7-8 is a horrifically nasty surprise near the end of a hard level. You're almost at the end of the level that you've already wasted several lives on... only for some asshole plant to set you on fire, leaving you to try to beat the level again.
 * Ensemble Darkhorse: The Koopalings went on to become an entire Darkhorse Ensemble.
 * However, the TRUE ensemble darkhorse is Kuribo's Shoe. Despite appearing in only one stage, of one level, of one game, it is enormously popular.
 * So much so that some fan-made hacks, such as Mario Adventure, made sure to let it carry over to every level.
 * Even Better Sequel
 * Fan Nickname: Even though the DIC cartoon of this game has been dead for two decades, many fans still use "Doomship" to describe not just the airship levels, but the ships present in Super Mario Galaxy and other future Mario games.
 * Game Breaker:
 * The P-wing, which allows you to fly over any level (except 7-4 or World 8's fortress). Beat the game and you can restart it with twenty-eight in your inventory, enough to make the hard parts of the game a cakewalk.
 * Kuribo's Shoe is a possible subversion. The shoe is a game breaker in theory, but it's only found in one level, and that level would be easily clearable without it.
 * The Hammer Suit, as it allows you to kill most enemies that even fireballs can't kill (such as Thwomps, Podoboos, and even Bowser).
 * But it is rare, and one hit and it is gone. Also you can't slide down hills while wearing it.
 * On the other hand, crouching makes you immune to small fireballs, just like a Buzzy Beetle. (Bowser's fireballs still hurt you, though.)
 * It's possible to swim under the ships in world 8's navy level.
 * Running full speed ahead into the goal card always gives you a star card, three of which grant you a 5-up.
 * Good Bad Bugs: The "extended 1-up" glitch that occurs when the tail-wag sound and 1-up sound are merged.
 * There are numerous places in World 7 (often allowing full-stage skipping), Bowser's Castle, and elsewhere where you can walk through a wall. See this video for a sampling.
 * Hilarious in Hindsight: The goombas are called kuribos in the Japanese versions of the series (hence Kuribo's Shoe). So the tiny ones in this game would be Little Kuribohs.
 * Nightmare Fuel: The music that plays when you read the letter from Bowser before World 8.
 * World 8 itself is surprisingly creepy itself. For lack of a better term, you're pretty much in Hell itself, complete with black skies, boiling lava as well as water that suspiciously looks like blood, and bigass hands that seemingly pull you into the abyss... though they only take you to short, easy to beat levels. Many a child has been unnerved by this world on their first run.
 * Polished Port: Super Mario Advanced 4 is a very solid port, allowing you to play it on the go while handling just as great as it did on the NES and SNES. It also got a ton of new levels with special powerups that could be accessed through the e-reader, and while not many people got to play them as a consequence, they all became freely available when the game was ported to the Wii U.
 * That One Boss: Among the Koopalings, Wendy can be considered the hardest of the bunch. She jumps incredibly high and will summon candy rings to bounce around the stage to guard her while you fight her. The more damage she takes, the more of these she summons, so the battle can get pretty hectic if you're not careful.
 * Ludwig and Roy are also trouble because of the tremors they create when they jump, which is often. If you don't jump right before they land, the tremor will stun you leave you wide open for them to hit you with a wand blast or collision damage.
