Are there any games like Street Fighter? I think a street fighter type game could work for the iDevice? Random Examples: Drawing a circle could be a round house kick. Slide up = upper cut Tilt to move left and right? Tap the right side of screen to punch tap left side to kick Slide up slide down tap tap circle = Some super move?
After all of the games I've been playing on the iPhone, I think any game would work. You should wait for the new Gamevil game. I forgot what it's called, but it's quite like Dragon Ball Z, Taiketsu or Super Sonic Warriors. Look into it, why don't you.
There is one game like this but it sucks and got like 1 or 2 stars... Ive been waitin for somthin like this myself..
Don't forget Blades of Fury, Gameloft clone of Soul Calibur. Quite impressive actually given it was released in September... 2009!
