My overall opinion for this game is a bit disappointing.
I have played Melee & Brawl at competitive levels.
Base on the 3DS demo:
1) Extremely floaty (Expecting the same from WiiU) - it might change with certain character due to their weight but still very floaty.
2) Awkward Button placement
3) Bad on D-pad (Rubber Fell)
4) DI is way too easy in this game.
5) Lack of a Gamecube controller
I'm just trying to unerstand some points, not to bash or anything:
1)Did you play previous games recently? I have been playing Brawl a lot recently and I don't feel like it's floaty.
2) This one will indeed vary from person to person depending on hand size and preferences. Seeing as you have a small 3DS, you may want to try it on an XL for more fun.
3) I haven't had any problem, but that sucks
4) Did you play with three lvl9 AIs?
5) Lol
