As with most CC lists, a bit too much Stars Wars influence on that list for my tastes.
For me it was:
SimCity 2000. Hours and hours and hours on this.
Civilization was also a great one.
Indianapolis 500: The Simulation. Came out in 89 apparently, but it was a 90s game for me.
Nascar Racing 1 and 2. I hate Nascar in real life but this was fun to play and you could create customized paint schemes which was great. Also one of the first online multiplayer games for me.
Microsoft Flight Simulator. The most interesting part of this was not flying it seriously, but finding new ways to crash.
And also a ton of fighter combat type games like Janes Longbow 2, F15, Falcon, F117a etc.
Stunts. Great game as you could built your own stunt course.
Descent 1 and 2
So basically either games with things that moved fast or where you build cities.
