I don't base my purchases based on a review score, but rather the overall description that the reviewer gives...
The fact that I'm waiting for the C3 review is that I know it'll be written by a hardcore Sonic fan, which I am definitely not. I liked the classic Sonics and the levels from Sonic Adventure 2 where you were controlling Sonic (the other levels, not so much though). Since I'm not a fan of Sonic in general, I'm waiting to hear more about the game content from someone who I know will write a good review for it.
Yeah, sorry, I stopped basing my purchases on what's written on the packaging in the late 90's .
