Summary: My 6 year old son loves this. It isn't the traditional sonic b/c you have 4 teams (with 3 players each) to choose from to complete your levels. One team member flies, one has "power" for punching, and one is a speed member. It gives it an interesting twist on the sonic world.
Summary: I would post a long write-up for this game. However, I am simply convinced that Sonic in HD isn't really what we need. The simple days of Sega Genesis are gone and now we have crazy transitions and somewhat fancier environments. This actually doesn't help the feel of the game - surprisingly. I never had the feeling that I was going to have an epilepsy moment when I was a kid playing Sonic 2 on Genesis, but this game actually gives me motion sickness.
