An old-skool style mini-game to sell hosts & clients... I'm thinking something along the lines of the old Dope Wars game. (Travelling to different cities to get the the highest price, etc.)
For example; Hackers can get more cash for hosts & clients by selling in a NetGuard territory/district/city, but run the risk of being caught and losing a percentage of hosts & clients... or can play safe and sell in there own area with no chance of being robbed but with a smaller payout, and vice versa...
