When I first bought this I hated it. It felt wrong, looked wrong and didn't play well, but being a Street Fighter 2 fan, I gave this time and it blew me away.
Each character has been developed perfectly, with agility, strength and speed accurately based on the fighters style. The Super combos are great but the ultra's are excellent (Chun-li's and Fei Long's amongst the best)
With hidden characters to unlock, a crazy boss to fight, unique challenge modes to help enhance your fighting ability and also to release numerous colours, this game has to be the best fighting game in a long time.
The story modes are okay, with manga style cuts, though these aren't excellent and the deletion of both bonus rounds and characters unique stages is a let down but online mode makes up for that and of course, two player battles are never dull.
Give it a chance and it will really impress you. The more you play this, the better it gets.
Looking forward to Super Street Fighter 4, with at least 8 additional characters!!!!
