Sonic 2 is the best game in the Sonic Origins Collection. The soundtrack and momentum based platforming are amazing. 100% completion wasn't that difficult either with the collection's retry system. It introduced series staples like Miles "Tails" Prower and Chemical Plant Zone. My only complaints about are the final boss has 2 parts, no checkpoints, and one-hit kills; and the special stages involved a lot of trial and error (even to the point of emptying me of all the retry coins on one occasion). Regardless, this is one of the best sonic games ever made and the point where SEGA understood what makes a Sonic game.
