I only played at one tournament. I won. :P But it was a pretty n00bish tournament so nobody had really heard of Wave Dashing or tier lists. (I didn't Wave Dash.)

Just playing for the hell of it is SO much more fun.

Actually, tournament play is like playing a dumbed down version of the game. There are only a few stages, some characters are banned, and there are no items. Cutting stuff out of the game isn't fun. :P
