This has got to be my favorite traditional fighting game of all time. I haven't touched street fighter very much since the SF2 days, aside from just dabbling with some of the games now and then.
For the past several years, I've just really wanted to get into fighting games, and I bought like 10 of them, usually on steam sales. The only one that I was really able to get into was Power Rangers battle for the grid, and I eventually got tired of that because at high ranks it's just 1 or 2 touch kills.
I bought street fighter 6 hoping that it might be "the one"... And it really is! Not only is the gameplay great, but this game is the complete package. So many other fighting games are totally barbones, and don't ship with basic features. Capcom just really knocked this one out of the park!
