Another game suggestion I would have is
Hardwar . It's in the same vein, except that instead of piloting a spaceship, you pilot a solar-powered moth through a colony world covered with craters. The most amazing thing about this game is that the detail of the economic simulation is amazing. Raw resources get produced at mines and such and are actually transported by AI pilots to factories to be transformed into manufactured products (engines, components etc.), which are then transported by other pilots to shops to be sold. Human players can bounty hunt, trade, pirate etc, and even buy their own hangar, which they can then open to AI pilots to use to repair or buy things at for a fee.
The main problem with this game is that it's quite short and there aren't very many upgrades and new moths that you can buy.
