This game is actually really addicting. I got to *ahem* turn 1500+ and gave up. I managed to get 50% of the money to buy Earth, but the strategy required to buy it was too ridiculous. Basically I ended up at the stage where the best thing I could buy was Tundra, but that was always around 1% the value of Earth, so to win I had to buy at least 100 of them, but doing that is difficult because they only come up 15% or so of the time, so I had to shuffle the shop hundreds of times, and make sure my inventory didn't get filled up with too much crap (else the price of Earth might go up more than the amount you sold the other Tundras for). I gave up shortly after realizing this.
