As far as the overall Sonic community goes, SatSR was a rare 3D Sonic sucess. Places like IGN have labeled it as the best 3D Sonic game yet.
Personally, I'd say 8.5, pretty good.
What do you think?

Definetly A 10. It's An Awesome Game.

I haven't played it, but I would give it a ten even if I did like it as much as a ten, because it's the first decent 3D game since Sonic Adventure 2.

I give it a ten even though I haven't played it yet just because of all the gameplay on YouTube including DarkSpine Sonic. He looks awesome.
