As I downloaded and installed some Duke Nukem 3d (because I never got to play much of that gme growing up) I was thinking how there are very few games that can stand the test of time. Even the ones that were innovating and unique for their time, as improvements over the years made their older counterparts obsolete, I don't think I could see anyone booting up Civilization 1 if only for a few minutes before the novealty wears off (if you could even boot it up to begin with.) So I'm curious as to what older games you find yourself coming back to again and again or could go back to again despite thinking at one point you were done with them forever.
