I use to play a lot of fighting games online but now i just stick to UMvC3
I want to say Street Fighter can be more technical but then again i havent played a tekken game a long time
From going from Tekken to SF, SF seems much more simple, i was surprised with how few moves each character had as i was used to 100+ for each tekken character. Doesn't stop me from getting wrecked online though. I think it is because i am using Ibuki. I'm not even playing her because i like her fighting style.
