Old School SF2 fan here. This is a case of a very well designed re-release of the classic, put together by people who really love their Street Fighter. The presentation is gold class.
Unfortunately the whole thing is let down by the abysmal 360 D-Pad. Zero precision. The analogue stick isn't up to the task either. Grab a fighting stick controller and you are good to go.
It's a blast from the past. For those new to the series & all of those veteran players out there, like myself, this game puts a whole new edge on the old SFII system. With 720p enhancements, it's like having the old-school arcade system right in your own home.
One of my favourite bits about the game is the remixed soundtrack by the infamous Overclocked Remix group. If you haven't heard of them, then I would suggest you visit them at: www.ocremix.org They're a group of fans dedicated to remixing old video game soundtracks and releasing them freely on the web. I personally have their Final Fantasy VII: Voices of The Lifestream & their Chrono Trigger: Chrono Symphonic albums already downloaded. It's a great addition to the game while you're playing.
If you have some spare change in your pocket and love Street Fighter like I do, then don't hesitate to buy this game on XBLA.
