Well, the DS demo came out on the Nintendo Channel. Tried it out, despite the total similarity to Rush, minus the trick system, it's awesome. Then again, I liked Rush somewhat...
Anyways, I played through that biotch like 15 times before I got tired of it. If I can't afford the Wii Version in all it's 50 to 60 dollar glory, I'm going for DS.
Edit: Well, I actually WATCHED the videos...
Planet Wisp's music is pretty sweet. I'm loving the soundtrack for this game.
Also, Sonic's new sense of humor is great, even if the jokes are a bit childish, they're still really good. "Y'know, had to do a little shopping, grabbed a bite to eat, and smashed a giant killer robot."
Honestly, I really have to applaud Sonic Team on this one.
