@ purifier:
There has only ever been one good Zelda game. Majora's Mask for the N64. Zelda has always been a stupid idea with the exception of that one game.
See where I'm going with this? How can a single game in a series be good, while the other parts of the series that function on the same principles, like SA2, be stupid?
Anyway, I've never gotten around to playing Sonic 2006 (hell, I haven't even played Rush or Rush Adventure yet). Odds are I'll rent it eventually, if only so that I can legitimately give my opinion on it.
