* This game marking the [[VideoGame/SuperMarioRPG third]] [[VideoGame/PaperMario64 attempt]] at a Mario RPG caused a lot of rejoicing back in the day.
* Oh, hi Koopalings. Haven't seen you guys in a DECADE!
* Okay, time to fight [[FinalBoss the final bo-]]'''[[AwesomeMusic/MarioAndLuigi OH JESUS,]] [[https://www.youtube.com/watch?v=l32hDt6pLWo THIS MUSIC!!]]'''
* Baby Mario and Baby Luigi fighting alongside their adult counterparts.
* The DarkerAndEdgier storyline.

* Oh cool, a new ''VideoGame/MarioAndLuigi'' ga-'''[[EnsembleDarkhorse FAWFUL]] IS BACK?!?!?! [[DragonAscendant AND HE'S THE MAIN ANTAGONIST?!?!]] [[MemeticMutation I HAVE CHEERS!!!!!]]'''
* Playing as Bowser is awesome itself. He even has his own battle music to go along with it. Just imagine Bowser steamrolling through enemies. He's pretty much a killing machine ... although the enemies you fight while playing as Bowser have much higher HP than the enemies that the Mario Brothers normally fight, including [[spoiler:[[EvilKnockoff Da]][[FinalBoss rk]] [[EldritchAbomination Bow]][[TheDarknessGazesBack ser.]]]]

* The ContinuityCavalcade: within an hour into the game, all of the previous games get a CallBack.
* The game's SequelDifficultySpike has been welcomed warmly by fans.
* You don't get to play as Bowser ... but you do get to see him as a serious RPG villain for the first time since Paper Mario. He even [[spoiler:betrays Antasma and eats up the Dream Stone to become super powerful]].
* Popple has returned to the series. [[spoiler: Yes, you fight him. No, he only gets normal boss music.]]
* [[spoiler: [[TheDragon Bowser Jr.]]]] is the [[BonusBoss final boss]] of the Battle Ring. It's a minor one, but fans of him surely rejoiced.

* Hey, a new Mario and Luigi game- IT"S A CROSSOVER WITH PAPER MARIO?! SOLD!
* Paper Bowser can talk again (after being [[TheVoiceless voiceless]] in the previous Paper Mario), and has [[EvilIsHammy his old personality back]], making fans of the original Paper Mario games very happy.
* Alrighty, ready for my first battle! I wonder what the battle theme will b-[[https://www.youtube.com/watch?v=CPO3M6BZyoY YES! YES! YES!]]
* Paper Mario has his Airplane and Sideways abilities from The Thousand Year Door!
* Not only are King Bob-Omb and Papercraft Luigi [[https://www.youtube.com/watch?v=c4GE6_MMjFI confirmed]], but ''the '''Koopalings''' have'' '''''returned.''''' Even better - [[http://40.media.tumblr.com/ac95255021463f7bd372356a62485499/tumblr_inline_nyaf14UMx91roeqim_500.png they can also speak]] unlike Superstar Saga.
* Bowser Jr and the Koopalings get important roles in the story, without giving the shaft to the other, pleasing both fans!
* While the game doesn't introduce any original characters, it fleshes out pre-existing fan-favorites, particularly the Koopa Clan. The Koopalings all have unique personalities and [[SuddenlyVoiced speak for the first time]], Bowser Jr. (both of him) is an adorable JerkassWoobie, and Bowser himself (both of him) is [[KnightOfCerebus more competent and evil]] than he's ever been while still [[PapaWolf being protective]] [[EvenEvilHasLovedOnes of his son]].
* The Koopalings interacting with other enemies that they haven't seen interact with (that most fans probably wouldn't see them interact) seems pretty awesome by its own. Sure, Koopalings ordering a bunch of Chargin' Chucks doesn't seem new, but Iggy/Morton/Lemmy are shown teaming up with King Bob-Omb and even pilot (minus Iggy) a King Boo Papercraft.

''[[AC:VideoGame/MarioAndLuigiSuperstarSaga]] + Bowser's Minions''
* Oh, look, a Superstar Saga remake... ''A SUPERSTAR SAGA REMAKE''?!
* Fans disappointed with Bowser's ButtMonkey role in the original game were excited when the second gameplay mode, featuring Bowser's minions on a quest to rescue their master, was revealed.
