My only disappointment with the demo was that it only lasted 2mins. As for the full game, it seems awfully short from the leaked information so far. 7 or so different stages have been leaked, each with a 3d and 2.5d version. I dunno, but that seems like not very many stages to me. Maybe I was spoilt by the sheer amount of stages in Sonic Adventure 2.
Honestly I wish they'd just make Sonic Adventure 3. I never wanted it to go back to 2D. Despite popular belief it wasn't 3D which killed Sonic, Sonic Adventure 1 and 2 were awesome.
That said, I'm staying neutral about it. Sonic Colours wasn't that bad, though it did suffer from a lack of variety(7 worlds each with 7 acts... Less acts more worlds please).
