Great game! Kudos.
I think the game should be made a lot harder! Once you start making billions the game loses its shine. You can get the DEA and IRS under your thumb and then you are basically in god mode. Having the possibility of crippling setbacks would make the game more exciting. Also I think revenue generation should be slowed down 10 fold. After 24 hours of play I have a trillion bucks and not much to spend it on.
Cheers!
