I have to semi-agree with RedBiatch, because there is just no reason to keep playing. I am currently sitting in a position where my progress is literally clamped by cash. I have 99,999 resources. I am usually sitting on 999 research points. And I am just staring at the progress to the next planet because I can't afford another engine yet. When I get there, I'll throw people at all the missions and collect the money and maybe buy an engine and then I'll click the "start over" button. Nothing exciting is happening.
