Super Mario Galaxy 2, eh? Level design? Better. Hub world? Better. Level Themes, Gimmicks & Powerups? 10 Times the Awesome! Fluffy-Bluff Galaxy might even be sexier than Gusty Garden Galaxy! But.. There's one thing: The Atmosphere.. Lacking the power it had in the first game. However, I don't see this as an issue. Galaxy 1 is the only Mario game ever to ever have such good feeling world building. And it's a special case, Mario games are Mario GAMES. Not GAMES WITH REALLY AWESOME STORIES. That's only the case for Galaxy 1. You play Mario games for the jolly fun times, not the Galaxy 1-Level Atmosphere. You wanna get immersed? Go play The Last of Us.
