Yes, I don't think the actual models look bad, although the blended art styles suck, and if you look at some of the vids, you could swear sonic for the Wii does the desert graphics sooo much better.
And don't even get me started on the psp one... it's a racing game. That's it. RACING IN SONIC RUSH IS LIKE A SECONDARY FEATURE!!!! And it's really fun in Rush, and even works with download play. I mean, if the psp game was a REAL sonic game, then it would be interesting.
Once you play Sonic Rush, other sonic games just don't do it for you any more... you just go so darn fast... and amazing level designs and boss fights. The only sonic game I can see comming even close to toping it is the Wii game, and I honestly have some dbouts about the controls, although it looks like it will be the fastest 3d sonic yet. I'm sure I'll buy it, but I don't think it can top Rush.
