So I tried out the 2nd demo and from the looks of it, this is going to be one of the best Sonic games ever. Classic Sonic plays just like you'd remember him in the Genesis titles and Modern Sonic is more of the awesome Unleashed/Colors gameplay, but even better! My only complaint is that you can't turn Omochao's annoying voice off.
Also, to download the demo, you have to either have Xbox Live Gold or a EU PSN account (which i had to make just to download the demo) until it gets released on regular XBL and the US PS Store next week.
Anyway, who's getting the full game when it gets released?
