Chao garden on the gamecube. Countless hours raising those things to have them compete with friends. Probably spent more time on them, or at least collection things to raise them, than the actual game.
Truth is though while I like some sonic games the series has never wowed me. Always felt sonics rise to fame was more to do with Sega fanboys needing something to throw at Nintendo fanboys when they brought up mario. Hopefully he eventually ends up with a game that prooves me wrong.

Playing Sonic 2 almost every Saturday. On another note: there was a glitch in Metropolis Zone where Tails would be sliding along the pipes in the background. Me and my friend were playing coop together and somehow we lost Tails. Not sure if he just died that many times or if he walked into those gap-less death traps too often. It was one of the most bizarre things I've ever seen. The most perplexing thing is that it had Tails in a very specific animation so it had to have been planned.

Sonic Generations was a great game, and I hope to see more games like that. In the mean time, Sonic Boom doesn't seem to be looking good.

Good list, (Unleashed at #5 is proof of him having an interesting opinion :P) but it could've been a little shorter..

Unleashed at #5 bugs the living hell out of me, but I will give him a pass because Sonic 3 & Knuckles is indeed the best Sonic game!

That's why it's interesting. You don't see Unleashed in a top 5/10 of Sonic games often.

Happy Birthday Sonic :C Maybe its time you retired?

Happy Bday, only to you, 2D Sonic.

Maybe because the game is not enjoyable ny any means?

My favorite memory is when I played Sonic Generations and remembering how good the old games were
