Seriously, SRB2 is undoubtedly the best 3D sonic game ever made - fan or otherwise. (Although I've never played Unleashed, it sure beats Adventures 1+2, Heroes, and 2k6 in terms of being an actual classic sonic game.) The level design reeks of classic Sonic, along with the graphical style. The controls might be a little iffy but it's got a great community, awesome music, and some really sweet unlockables that show off some amazing shit - they've even got an entire NiGHTS engine built in. Fuck. How could you possibly dislike this game and call yourself a sonic fan? I'm really interested to hear what people who hate it have to say.
