I like SFxT, yeah.
I think there are some apparent technical issues (sound online, 360 controller, 360 co-op) that should hopefully be fixed at some point. It's poor on Capcom's part that the game was released in the current state. I hesitate to say 'rushed,' but it needs a patch.
My feelings on the game itself are that it's fun despite all the problems. Some characters are overpowered, some combos are too good, timing out in win or loss sucks... But I'm still having a good time. I'm not great at the game (1000BP only), but my opinion is higher now than it was a few days ago. Initially, I wasn't too happy with. Tekken characters, mid attacks, cross rushes, combos, gems... It just didn't make sense, it wasn't SFIV. I'm fine with it now, though. I have a better handle on the game, some of the characters, and how it all works. Wins feel good, losses aren't as frustrating.
This definitely won't be as popular as SFIV, but hopefully people stick with it instead of retreating back to something more familiar.
