Easily Sonic 2 wins this for me, and I admit I was a big fan of Fable when it came out, Fable 2 is better though, but that's a discussion for another day. Sonic 2 was a first for many things to me. It was the first Sonic game I had ever played, it was also the first Sega Genesis game I had ever played. I played the hell out of it when I was younger, always trying to beat it. It made me a lifelong Sonic fan, well with the exception of the shitty games they've been releasing lately. But that doesn't take away from the quality game that is Sonic 2.
