ultima underworld! It rocked the dungeons where so cool, I still do not think they have been topped, even by games like morowind and EQ. Fantastic game.
Wing commander one. What a visually stunning game that was for its time... Lol I hade to make a boot disk to get it to run on my 386/25 lol Origin sucked for memory management.
their finest hour Hours and hours on this one and secrets... nothing like getting 10 kills in a mission in a 110!
Fallout. Fantastic, great story, great tongue and cheek sense of humor, great interface!
Wasteland. What a great game for its time, I still remember making copies of disk 4 over and over on my apple 2 so I could get the power armor from the one temple for my whole team.
and Xcom.... man the first time you whole team got nuked by a blaster bomb just sucked! Or the first time one of your team got turned into an alien, the fire spreading through fields was awesome too..... I want to play it again!!
