Dope Wars

Inspiration

Dope Wars takes its inspiration from Taipan, where you play a trader in the ancient China Seas, trading resources from the mundane (silk) to illegal (opium), while surviving pirates, thieves, and the racketeers that demand protection money.

Another inspiration would probably be the 1984 interactive fiction game called Drug Wars. So similar in fact, you might as well call it (roughly) a total rip-off in the concept (there's got to be a copyright violation here somewhere, maybe).
