While I like Super Nintendo a lot, I also like the Sega Genesis. It had some pretty cool games aside from Sonic.
You have great arcade ports such as Golden Axe, Ghouls 'n Ghosts, Strider, Altered Beast; pretty unique games such as Kid Chameleon, Decap Attack, Ristar; Popular games such as Streets of Rage, Gunstar Heroes, and a nice 3rd party support with games such as Contra Hard Corps, Castlevania Bloodlines, Street Fighter 2, and it goes on.
Not as awesome as the SNES, but Sega Delivered with this console.
