Hm, it took me quite a while to write that review of my favorite game. I have no idea what I'll say for my most disliked game. I've never really played a game that I hated, because I only buy a game if I'm sure I'll enjoy it. =/
Well, if I can still join this, I might as well.
My five best characters would probably be:
1. Ike
2. Lucas
3. Luigi
4. Ice Climbers
5. Meta Knight
Although I almost always end up using Ike in online play.
