I don't want to take anything away from what looks like it could be a great game but, the increments seem rather big, $150,000 for 'metal' planets.
And yet for $100,000 they gave water planets and naval units?
Really makes me wonder how much funding this game would have got using the traditional methods of investment.
Your numbers seem a little wrong..
Also, the 'metal' planets are actually space stations that you can reactivate, which is a substantial addition I think.
