How much you enjoy this game is really going to depend on how much you enjoy the combat system, because let's be real, the story is non-existent for 90% of the game. It only exists outside the disney worlds, and when it's there, it's pretty good. As for the worlds you explore, they're the same as in KH 1, with the exception of Twilight Town.
So let's talk about the combat then. As the rating tells, I like it, a lot actually. Sure it becomes a spam-fest by the end of the game, when all your cards are better than your normal enemies' cards, but it makes for some real good boss fights. They're tense, they force you to adapt your deck (are you going to try and play the long game with more, lesspowerfull cards, or try to force your way through with strongern but fewer cards ?). It forces you to strategise and apply that strategy in the fire of action, which can be really tense. It's a fun experience, at least in my eyes.
(Spoilers for post-game)
As for Riku's gameplay, it's a nice change of pace for the first few hours, but does get pretty boring pretty fast. It's nice to not have to build your own deck at first, and your deck changing between worlds and being imposed to you is a pretty good idea, forcing you to adapt, but the fact that only two types of cards exist really makes it boring pretty fast. It's a simplified version of the gameplay, which is nice for a post-game campaign, but it's simplified to a fault a few hours in. Shaving off a few hours could've been a good idea. I still like the fact that this campaign is here though, as it's probably a better story than the main campaign's one.
