I say I love Streetfighter, but this is the only one I've ever invested any time in haha...Hakkan is seriously so great though, how can you resist Turkish oil?
I love fighting games but I never have anyone to play them with that is at a similar skill level. I also don't have the time to invest in them because I'm already too invested in a bunch of other genres.
Street Fighter IV might be my favorite Street Fighter game I've played... but that isn't saying too much, as I don't have much experience with the franchise, nor many hours in this game. Was enjoyable for a non-fighting game fan.
