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.

4 comments by SimMars on May 25th, 2011

The Terraform 1000 add-on package is a designed to simulate the changes apparent in terraforming a desert world into a habitable environment, a process that may take more than a thousand years.

The Terraform 1000 mod is fully compatible with SimMars and SimCity 4. It can also be used in combination with other rock and water mods.

There are three different terrain stages in the Terraform package:

Terrain 1 – Sandy Desert

Terrain 2 – Water

Terrain 3 – Green Beaches

It keeps crashing I tried running it in compatibility mode and that does not work at all so far the crashes I found were when I evict a citizen and when I go to the options. I use a Windows 7 64 BIT HP Pavillion.

What version of SimCity are you using? Also, is it a legit copy (non-cracked).

Yes it is legit and I did not update it when I used it, also does it need rush hour?
