Mars Simulation Project

Here's something cool I came across a while ago: the Mars Simulation Project. Not exactly a game, but at least game like, it let's you simulate a human settlement on mars complete with exploration, advanced base-building and social interaction, resources to manage, an economy system, etc, etc. It seems very advanced yet with an accessible UI and nice graphics. There are several scenarios to run and loads of little details to track and optimize. This should be fun!
