Yeah I have Sonic Adventure DX and Sonic Adventure 2 Battle for the Gamecube and I've played them to death. And I started playing them again after my original Files on my old memory card somehow got deleted, now I got to do everything again. And by everything I mean EVERYTHING. I had over 300 hours logged into both those games combined, which might be the only reason I get SA2 for the 360, but I'm thinking about not because they aren't the same but they're very close to it, and as I said before, I already have it.
On a different note, am I the only person who thinks they should make extra DLC for Sonic Generations? Like extra levels and stuff like that. If they do I'm hoping they remake Sky Deck from Sonic Adventure, or Hydrocity Zone from Sonic 3.
