So what are people's impression of the game now that it is out on Xbox 360 Arcade? I'm only up the third level but I'll give a quick rundown of what I've experienced so far.
-I had the US version so my soundtrack was different from this version. The soundtrack is good but, for mostly nostalgic reason, I miss the old soundtrack. This version doesn't even have Sonic Boom!
-The graphics look great. They did a really nice job with the update. Plus it is nice to finally play this game with a good, solid frame-rate.
-The game is still really, really fun.
EDIT: Thanks to resifreak for reminding me. I'm also really happy that this game is $5 (400 MSP). I was expecting a Sega-tax and a higher price point.
