Eh, I dunno. Rarely play any games older than '90. Super Mario Bros. 3, I suppose? I think that is the oldest game that I still play every now and again. Honestly, I find it very hard to play any game released before '90. I tend to avoid most of the stuff from before that era like the plague, since I know that every single game I play from then (with the extremely rare exception) I will hate. Not because of the graphics, more because of how poorly designed they were, how crap the controls were (especially PC games), how crap the interfaces were, how crap the stories were, how punishing they are, and just how damn simplistic most were.
