I had no idea how much it costs to run an evil facility. My minions work for free, nothing requires money to maintain and yet I still have money problems because everything is so expensive.
Not a bad game, both relaxing and yet frustrating at the same time. Relaxing because the game flows quite well, but frustrating because there is always something holding up your evil plans. With me this is always in the form of a cash flow problem.
TIP: Check the Global Map often (like once a minuet).
