Wow
The amount of disdain for this demo is a little bit suprising. I have to say that it didn't exactly rock my world either, but I think you guys are being a little overly harsh on it. First off, it's just a demo, and secondly, it's a very short demo, you don't really get to see very much of the game. Ok, so maybe this isn't the return of Sonic to his former glory, but it could still be a decent game, especially for those of us with kids.
I have two little rugrats, and the only 360 games I can play with them are Kameo and Lego Star Wars II. The rest of the games are too adult, and they are too young to be into racing or sports. I look forward to games like this, because these are the games that they are actually excited to play. I let them try out the demo, and they both loved the demo. My 6 year old, kept wanting to play that short demo over and over. He couldn't get enough of it. I will personally admit that it's not what I'm looking for in a Sonic game, per se, but if my kids like it alot, I know I need to at least rent it for an extended period, so they can mess around with it awhile.
