I just want the worlds to be good and for the grind to either not exist or not be garbage. Like, KH1 had cool worlds, but they weren't big enough and got repetitive. But they had all sorts of cool goodies and exploration rewards. KH2 had huge open worlds, but it felt like nothing was in them. BbS had really cool worlds, but the problem was they were over far too quickly. I haven't played 3D yet, but I'm betting that suffers the BbS issue.
Also, fuck melding commands in BbS. Like, in theory it was a good idea, but I'll be damned if I play another Command Board.
Also, if we're going to get a mini-game world, it best be Hundred Acre Wood. I mean, they tried with Disney Town, but that world was pure, undiluted garbage. I will stake my life on that being the single worst world in any KH game. Followed reasonably by KH1 Atlantica and KH2 Pride Lands.
