The theme for this year’s Game Design Challenge was enough to make a game designer blush: the first time they had sex.

Every year at GDC, the Game Design Challenge tasks a handful of designers with creating a game around a specific concept or object. Past years’ challenges include making a licensed game for the poetry of Emily Dickenson, creating a game that used fabric as a controller, or designing a game to be played with an animal. This year, a trio of developers were asked to design a game around their first time in the sack. There were a few rules, of course. There was really only one restriction – the game their game concept had to be playable on existing technology. Keeping their games Wal-Mart friendly wasn’t technically part of the rules, but the participants decided to err on the side of good taste, anyway. For the most part, that is.
