Yes. It's good to try different fighting games even if you end up not liking it. So far I've played skullgirls, virtual fighter 5 FS, tekken 6, SC, and street fighter ultra.
Well, I played DoA4 before SCIV, and also UMvC3 between IV and V. I've played nearly every fighting game, except for any GG and the latest BB, but only gone into those in depth.
I've tried a couple of times before with SF, but the game makes very little sense to me. I'm pretty much stuck playing as El Fuerte as he break a lot of the rules it seems, but I never feel like I learn as a player using him...
I feel that of any fighting game, this would take the longest for me to learn, that's all.
