History VideoGame / SuperMarioGalaxy2

* BossRush: Boss Blitz Galaxy in the Special World has one of these against five of [[VideoGame/SuperMarioGalaxy the first game]]'s bosses. Specifically, [[spoiler:[[WarmUpBoss Dino Piranha]], [[LethalLavaLand King Kaliente]] (both from the Good Egg Galaxy), [[TunnelKing Major Burrows]] (Gusty Garden Galaxy), [[GiantHandsOfDoom Bouldergeist]] (Ghostly Galaxy), and [[IncendiaryExponent Fiery Dino Piranha]] (Melty Molten Galaxy),]] in that order. They are even accompanied by their battle theme tunes from the first ''Super Mario Galaxy''.

* MarathonLevel: Clockwork Ruins Galaxy. Numerous traps and hazards must be sorted to get the main star. So many that, for those wanting to hurry to beat the game, it's easier to proceed to the next galaxy by ''getting the hidden star''.

* UniqueEnemy: There is a single spiked Cheep-Cheep rolling towards you in Cosmic Cove Galaxy. It doesn't serve a purpose for any star.

** '''Secondary''': 1-Up Mushrooms, Life Mushrooms, Purple Coins, Silver Stars (5 for a Power Star), Comet Medals (2-only).
** '''Tertiary''': Star Bits. Launch Star Pieces. Coins, Notes.

* FakeLongevity: The Green Stars, which send you on a scavenger hunt through all of the preceding galaxies. Nothing new is added. And to make matters worse, the Green Stars operate under one comet, meaning all of them (unless one is in another mission) will be on the map if you select one Green Star mission. However, only one Green Star can be collected per entry, forcing you to enter the level two or three separate times to get every Green Star, adding to the already-manufactured length.

* FakeDifficulty: Present in most of the Green Star missions. Some of the Green Stars are located out in space, requiring you to make a LeapOfFaith to get them (and if you don’t get them, you’ll die) and due to the occasional bad camera angle, it's next to impossible to gauge with any degree of certainty exactly where you need to aim your jumps. Flipsville Galaxy's third star [[note]]where you have to fall upward from a gravity-reversed platform toward a star you can't really see, in 3-D space, and where the slightest error means falling to your death [[/note]] is one of the best examples.

* PivotalBoss: Subverted by the Boomsday Machine, as it becomes mobile once you get two hits on it. Megahammer and Squizzard are straight uses of the trope, though.

** Giga Lakitu plays a [[https://www.youtube.com/watch?v=06LOPcTeF5Y frantic theme]], later borrowed by a duo of Stink Bugs in Puzzle Plank Galaxy.

** Same example [[VideoGame/SuperMarioGalaxy as last time]], condensed into one level: [[spoiler:[[BossRush Boss Blitz]], which begins with [[WarmUpBoss Dino Piranha]] and ends with [[IncendiaryExponent Fiery Dino Piranha]].]] Also, because [[spoiler:Boss Blitz is only unlocked after [[TheVeryDefinitelyFinalDungeon Bowser's Galaxy Generator]], Fiery Dino Piranha is the [[BonusBoss last boss in the game]]]], while Peewee Piranha is the first.

* ShesAManInJapan: Lubba is actually dubbed a female in the German version of the game.

* {{Speedrun}}: [[invoked]] Some prankster comets will impose a speed challenge on you in order to snag a star, and it will cost you a life should the clock run out. There are two types of speedruns in this game: One's a TimedMission and usually has an added gimmick, the other has you start out with a very tiny time limit which you have to increase by collecting clocks throughout the level.

* DamnYouMuscleMemory: The [[EverythingsBetterWithSpinning Star Spin]]. The control itself is unchanged, but several new levels and features seem designed specifically to punish those who are too reliant on it — notably, the platforms in the Flip-Swap Galaxy ([[spoiler:and later, the Flip-Out Galaxy]]) and the limited-use Cloud Flower. The latter is particularly nasty in Shiverburn's [[spoiler:Green Star 3]], where you have to grab a Cloud Flower in the first section and reach the third section while retaining at least one cloud, meaning you effectively have to navigate a long section of moving platforms over lava damageless and spinless.

* {{Speedrun}}: Some prankster comets will impose a speed challenge on you in order to snag a star, and it will cost you a life should the clock run out. There are two types of speedruns in this game: One's a TimedMission and usually has an added gimmick, the other has you start out with a very tiny time limit which you have to increase by collecting clocks throughout the level.

** World 6 features some {{Breather Level}}s ''and'' a large DifficultySpike. On the one hand, Slimy Spring Galaxy and Throwback Galaxy are relatively easy (though this may be justified in the latter's case, given its NostalgiaLevel status). On the other hand... Clockwork Ruins has likely the [[MarathonLevel longest mission in the game]], the second level of [[LethalLavaLand Melty Monster]] has been known to [[ThatOneLevel drive players up a wall]], and Battle Belt features a boss fight against [[ThatOneBoss Fiery Gobblegut]]. And finally, reaching the FinalBoss requires 70 stars, so if you've skipped most of the optional missions, you'll need to go back and finish them.
