>is CD any good
I personally hated CD. Thought the PC port is amazingly good though. Fixing some of its more blatant flaws, has saving, tails mode and access to the American and Japanese tracks.
S3&k is my go to game. 1 and 2 are great as well. I would recommend just playing it all in order. CD and S3&K are kinda rivals for the top classic sonic game [or sonic game period].
1 is the slowest paced, 2 is all about FAST, S3&K is more balanced with a bit of both, CD is more about exploration. Try em all and see how it goes.
