Sonic 2 was my very first consol video game and is one of my favorites. I got most of the others but sadly not all of them work anymore.
I must say that Sonic games really started going down the drain when he went to dreamcast. They ruined knuckles by making him a gullible looser that listens to rap. And they call Dr. Robotnik just Eggman now, terrible.
Plus Sonic 3d sucked too(that one with all the little birdies)
