My favorite games were
Sim City 2000
Scorched Earth
Jill of the Jungle
Corncob 3D
Wolfenstein 3D
Jazz Jackrabit (we got this with our first computer, which was a 486)
I even had an old XT that we got from my neighbor that had like all of 512KB of memory and we set it up as a dedicated gaming machine with the likes of Pac-man, Frogger, and all sorts of other arcade games.
