I just got my copy of Street Fighter IV in the mail today. I played a few games, so far I am really impressed. A lot of fun, the new focus attacks are cool, and the super and ultra combos are really rad. I will be competing in the game battles ladder and broadcasting live via justin tv (my vga adapter converter is in the mail...).
I wasn't going to spend the money on it because I already have street fighter games. But that was dumb, I got all into it after watching some vids and the need for something different. So I went online and ordered it. And I am glad that I did.
However, I have to really adjust my style of play with Zangief, he doesn't play the same as in SF2 Turbo and other SF2 variations. So I will need a couple weeks to get it down. I was getting owned last night on XBL. His super and ultra combos are just monsters though, if done at the right time you can take off 2/3 of someone's health.
