Xbox, Wii, PlayStation 3, SexBox? An integrated circuit manufacturer appears to be working on the SexBox, a console designed to play AO-rated games.

Silicon Xtal Corporation, located in San Jose California, registered the name SexBox in the US for use with a “video gaming console comprised of computer hardware with unique controls which plays Adult Only rated (AO) video game software titles.” Can’t get much clearer than that. The trademark description also explains the device may be used as a gateway to other adult entertainment and massive multiplayer online games. Wait, massive multiplayer adult games?

The company behind the proposed device says they worked on the Xbox 360 hardware. Microsoft probably won’t be amused with their choice of name.

Platform holders Microsoft, Nintendo, and Sony have not allowed any AO rated games on their console. Stores don’t carry AO games either. Titles rated Adults Only by the ESRB, such as the Indigo Prophecy: Director’s Cut, were sold and distributed online. The number of AO rated games is few, but there isn’t a device like the SexBox on the market to support them. Anyway, it doesn’t sound like the SexBox is designed to play Indigo Prophecy…
