Summary: The king of fighting games. Nothing compares to the depth, mechanics and meta game of SF4. Best of the best. A game with millions of fans. Inspiring people to get better and to know more and study it. Never gets boring.
Summary: I say that SF IV is one of, if that isn't the best fighting game of 7th generation. The game is very nostalgic, and has a wonderful gameplay. The fighting games fans must have respect to this title: Ed Boon said that the greatest inspiration to Mortal Kombat 2011 (9) was SF IV. You don't have to like, but, at least, show a little respect to SF.
Summary: The best fighting game of this generation of gaming, bar none. Graphics, Sound, Controls are all top notch, and while I'm not going to say it's better than 2, it has single-handedly restored interest in what was a failing fighting genre.
Summary: Incredibly unbalanced mess of a game with characters so similar to each other, that there is no point in playing more than one. I regret buying it, since there are much better fighting games out there (Tekken and Mortal Kombat to name a few)
Summary: Although it's nice to see this game being released on PC as well as the consoles, the PC version unfortunately has more problems. The game is laggy on both PS3 and Xbox 360 versions, but on PC it's simply unacceptable amount of lag. The graphics don't look far different either. The biggest problem however is that you need the disc to play if you bought a retail version.
Summary: It may not be a balanced game and online is laggy, but as a whole Street Fighter IV is a remarkable game which can easily be recommended to players of all skill levels and those who haven't played a fighting game before, due to its variety of modes and characters which accomodate for different playstyles. On PS3 versionj you don't need to install it either. Definitely worth checking out.
