Woohoo! I just found Sonic Adventure DX for 5$! Of course, the disc is scratched to hell, but if it still works it's one hell of a bargain.
The SA games are of course flawed, like any games (SADX forces you to play as *Big* in order to get the true ending, which is about as horrible as it gets; SA2 has those tedious treasure hunting levels with Knuckles and Rouge) but they're still both the best 3D Sonic games in my opinion. Heroes looks boring with a really kiddy story, while Shadow features weapons, vehicles, tons and tons of 'radical angst', and a story that completely retcons SA2's backstory.
Anyway, the worst thing now is that I have to wait until next week to play my Wii for the first time.
