I ran out of patience waiting for the career mode to come out, so I'm doing it myself. I will be starting with 50,000 dollars and will take jobs as far as I can manage.
For the first one, the contract was self-imposed. However, now I will open the floor to all offers. Post a feat you want accomplished (a comsat network, or maybe a personal space station) and how much you bid to get it done, and if it looks profitable, I'll tackle it. EDIT: Okay, that's a lot of contracts.
