Oh, how could I forget - BIOFORGE!
I've got that running in Dosbox. I've had that since 1995. You know, I'm stuck. There's a mech on every floor that kills me. I can even go to the surface but some floating bots zap me dead. There's the cyrogenics room with the mecha-raptor, and the tunnel beneath with the thing in the hole that instantly kills you. I've been stuck there since 95.
