I know, it's a game and it was okay. The concept that humanity could or would want to live on Mars is simply an impossible fantasy. We might as well try to live on Earth's moon, which is just as unsustainable, impossible and pointless. In discovering Earth-like exoplanets, what man should be striving for is figuring out a way to travel to them and overcoming or slowing down the aging process, in order to reach them while still alive.
