I like every Sonic game ever made, except for 3d Blast, Mean Bean Machine, the Tiger handheld LCD games, the Game Gear ones, all of the ones made after Sonic & Knuckles, Sonic CD, and anything I didn’t already mention but that appeared in the Sonic Gems Collection. Also the first one, because there’s no spin-dash. The Sonic The Hedgehog & Friends arcade game sucked too. I don’t like that one either. That one for GBA was okay though. So exclude that from the post-Knuckles group.

edit: Oh, the Shadow ones are **** too. And Sonic pretty much sucks in Brawl.
