Buy the pad or the fighting stick and just get going. The ps3 controller sucks dnu about xbox.
The combos in that game is alot about interupting your attacks half way and stuff with focus attack and dash.
Atleast it is for the chars i play most ryu and akuma. Ryu's best combo is like Heavy leg jump forward, medium punch close, Dragonpunch, focus attack, forward dash and timed ultimate before the body lands. Its not like tekken combos were you smash buttom after eachother in a serie

I didn't like sf4 that much. I like UFC more with all the 23456789 things you can do.
