Hello,,!
I know Simcity 4 has been released in 2003, but it's still very populair.
Look at: www.simtropolis.com. There are allot of downloads for your game. Made by normal people, not the makers of simcity. I like the game very much. Soon I will put some stuff on Deviantart, of my Simcity 4 cities. I will photoshop them to add some effects and all that.
