1. I included all versions of Street Fighter II as one.
2. No one voted for EarthWorm Jim (1 or 2) and that's a damn shame.
3. Sonic 3 & Knuckles were seperated since they were seperate game releases in 1994. But I'm totally with you in that S&K (and even moreso S3&K) is the definitive Sonic experience. (Which is why I usually have a Knuckles avatar!)
Oh, there was a vote? Well, that explains it all. And, Breakers was a fantastic game on the neo-geo. Too bad Breakers Revenge never showed up on the console. It would have sold 40 million+ more units. :P
But, you know, Sonic & Knuckles alone wasn't enough to keep me from Sonic 2. I always thought it was too short. Even when I first beat the game at age 5, or 6, or maybe 7... I was just left wanting more... but, when I got Sonic 3, things changed. It felt like the complete game I'd wanted. So, individually, maybe I'd put Sonic 2 on top, but Sonic 3 & knuckles as a complete game, completely beats out Sonic 2 in every aspect.
