Sim City 4?
But if that's not your thing I highly recommend....
The old Carmageddon games, I prefer 2. It's a light hearted racing game where you can choose to do the race, wreck all of your opponents(as if you'd do anything else), or find and run over every pedestrian to win(they do tend to fly apart on impact).
But as an older game it's not taking things seriously so it's an excellent time killer. As in a game where power ups are...low gravity, a spring that throws your car in the air, a spring that throws nearby opponents around and nitrous that makes your car too fast to deal with and frequently kills me. It's 3D with localized damage modelling so crumpling can be a bit entertaining especially since it's not just cosmetic so bent frames etc. And it has a car upgrade system too so really as far as gameplay it makes some of today's games look a bit boring.
Or maybe you'll just like the names of the races.
Race names: Beaver City/Quarry/Mountain..."Nice Beaver", "Eye of the Beaver", "Stoned Again", "Piste Off"
El Morte Desert: "Sheik, Rattle & Roll"
USS Lewinsky: Take a guess....."Going down"
You get the point. Unfortunately I don't think this is something new enough to find for sale but it can most certainly be torrented(at your own risk). It was working on Windows 7 last time I played but had to be launched from the exe instead of the launcher.
