It is SimCity 4 Rush Hour, by EA Games. EA games has no other worthy title which is not a shame, its suspicious.

I played Doom on a 386dx in 1994, after "id" released the source and it was ported to X.

It was awesome, the Slackware install was playing it like a champ on crappy Compaq hardware.

SimCity 4 is currently the pinnacle of city building games, nothing on the console online or in your imagination can surpass it. The MODs are still functional and awesome.

I play AD0 these days, not a city building genre but still beats the console or online.
