Zerg rush--$50

South Koreans are increasingly turning to the internet to buy sex. If I was shocked by this, I might ask them what took them so long? However, since prostitution probably hasn't been incorporated into the latest Starcraft patch, I can probably answer my own question.

Mental note for business idea: create an MMORPG or RTS for Korea with semi-legalized prostitution for the Korean market, except the women characters are actually women, instead of dudes simply playing as women.
