History VideoGame / SuperMarioGalaxy2

** The Boo Mushroom shows up ''once'' in the entire game. It doesn't even get a second appearance via Prankster Comets or Green Stars. The same can be said for the Spring Mushroom (which appears in only one galaxy for a grand total of two missions, one of which is a Green Star), but that's [[ScrappyMechanic more]] [[PowerupLetdown forgivable]]. Luckily, the [[KillItWithFire Fire Flower]] and the [[SuperStar Rainbow Star]], both of which are series staples, did not receive the same treatment.

*** Let's not forget Mario himself, who [[spoiler: punches a gigantic Bowser into a black hole during the final battle]].

* CallBack: In the third Bowser Jr. level, you come across the destroyed body of Megahammer, the boss you fought in the second Bowser Jr. level. [[spoiler:Its Bullet Bill cannons are still working, too.]]

* ChuckCunninghamSyndrome: Polari, The Spooky Speedster, Guppy, Topmaniac, Kamella, Kingfin, and Megaleg are the only characters from the first game that do not appear in the sequel. [[FridgeHorror Especially if you consider what happeened at the end of the first...]]

* Grandmaster Galaxy may probably count as well: The music for Sky Staton Galaxy (the first level in the game) is reused for the second portion of the last level (but not the last star), while the music for Good Egg Galaxy (the first level in the first ''Galaxy'') is reused for the second portion of the last star.

* {{Narrator}}

* WhatHappenedToTheMouse: [[spoiler:What happens to Bowser Jr. after you defeat him in World 5? Does he die? He doesn't appear in the game again after that.]]

* NintendoHard: Most of the game isn't impossible to get through, but many levels and challenges towards the end get quite difficult and are guaranteed to make you lose a handful of lives. World S pushes this even further with, for one example, one level having Thwomps and rolling stone blocks move at such inhumane speeds that you can't physically run fast enough to get by and not get crushed. Several switches in the level can slow down time for a while, but pray that it doesn't run out when getting by the instant stone crushers. All this was most likely a response to fans who [[ItsEasySoItSucks complained that the first game was cakewalk and gave no challenge.]]

** Many unused interactions in-game: The circular beam dissappears into the ground while in Ghost Mario form, for example.

** Wait, so, [[spoiler: reality was reset? Oh, OK. Hey wait, Rosalina ''remembers''! And was narrating ''the entire time''?]] [[OrIsIt So did it really happen?]] Wait, it had to have happened, the baby Luma still has his hat! …So how was she narrating?

* AGodAmI: Bowser's goal, though he doesn't state it directly, much like the last game. However, he takes it a step further, as instead of using the Grand Stars to power up reactors, he ''eats them'' to power ''himself'' up.

* NoOneHasAMemoryOverTwoYearsOld: No one put it better than [[ZeroPunctuation Ben "Yahtzee" Croshaw]] in [[http://www.escapistmagazine.com/articles/view/columns/extra-punctuation/8737-Extra-Punctuation-BAFTAs-Are-Bollocks.2 this]] ''Extra Punctuation'' column:
--> The general response to ''[[SuperMarioGalaxy2 MG2]]'' sometimes makes me wonder if I somehow crossed into another timeline where ''[[SuperMarioGalaxy MG1]]'' never existed, or was complete shit, and now I'm staggering through the streets in a beaten-up spacesuit yelling up at windows, "THERE WAS A FIRST ONE! IT WAS PRETTY MUCH THE SAME BUT SLIGHTLY BETTER! WHY DOESN'T ANYONE REMEMBERRRR?!!"

A direct sequel ([[spoiler: or CosmicRetCon]]) to the original ''VideoGame/SuperMarioGalaxy'', ''Super Mario Galaxy 2'' was released in 2010, three years after its well-loved predecessor. Like the previous game, [[SuperMarioBros Mario]] goes into space once again on a quest to [[SaveThePrincess rescue Princess Peach]] from a building-sized Bowser, who once again plans on creating an evil galactic empire at the center of the universe. Riding on a spaceship-planetoid [[{{Faceship}} built in Mario's likeness]], Mario must once again save the universe. Also, Mario's brother Luigi and their buddy Yoshi tag along for the ride.

* NotSoFastBucko: [[spoiler:See DisneyVillainDeath above.]]

* KillItWithFire: See DodongoDislikesSmoke.

* DodongoDislikesSmoke: You kill Squizzard by [[KillItWithFire hurling fireballs into his mouth]].

* MercyMode: The Cosmic Guide becomes available for some stages if you die too many times. It is similar to the Super Guide from ''VideoGame/NewSuperMarioBrosWii'' in this regard. However, any stars you get [[EasyModeMockery will be bronze instead]], which don't count towards your overall Power Star count, requiring you to eventually beat the level legit.
** Actually, Bronze Stars ''do'' count in the game towards your total (including enabling the 120 Green Stars), but if you have even ''one'' you can't unlock the [[spoiler:Grandmaster Galaxy]].
** Thankfully, there's no EasyModeMockery if it does show up in a level, unlike in VideoGame/NewSuperMarioBrosWii.

* LighterAndSofter: Compared to the first game, literately. Every point in the first game where there was a dark starry sky, there is now a blue sky with clouds in the sequel, even on the cover art.
