So far I only played the first level of Zone 1. (I downloaded it late last night.) I am really enjoying the game, however, Sonic doesn't move the way he used to in the Genesis versions. He looses his momentum really quickly. Just so you know, the graphics are pretty damn good. I (still) play on a SDTV, but yet the detail is really crisp. For you PSN+ users, I think you can rent this game. Give it a try. I think you all might like it.
