Just because I don't like the game, doesn't mean it's a bad game... It just did a lot of things differently. Out of the classics, I would say it's the worst though. Best being S&K, then S2, S3, S1 and then CD.
As for Sonic 06... Ugh. I am a pretty big Sonic fan. I'll buy the games regardless of what is said about them and make my own opinion. I've sat down and grinded speedruns on certain games, even achieving world records at times, so I'm pretty patient I'd say; But I had to kinda of force myself to finish 06. It was just rushed sadly.
