SimMars is a mod for SimCity 4 taking the game to Mars. It will bring new buildings, transportation systems, user-interface and music and will replace the Maxis SimCity 4 content as far as possible, giving you the feeling to play a colony on Mars. The mod is still at beta stage. Beta 3 was released in October 2010.

I'm very glad to see people are still making mods for this game, slowly but surely anyways. Network Addon Mod should go well with this gem :)
