I stopped playing computer games years ago, but I have very fond memories of Commander Keen, Keen Dreams, Duke Nukem, Crystal Caves, Wolfenstein 3D, Police Quest and a few more.
I don't know if it's just me but there is something about those games from yesteryear that have an appeal that the new games just don't have. Today's action games are too intense, require way too much time and way to much processing power. It's just not appealing to play a game that requires that much dedication and involvement...
Ah, yes, Wolfenstein on my 286 processor did run quite choppy
