Mine would be about the adventures of a NEET, where you play minigames consisting of: furiously programming, tagging music in a strict fashion, and obsessively checking torrents & Twitter (with a lifebar that would slowly drain if you didn't check them). If you attempt to leave the 3m x 2m room you are in for the duration of the game, YOU DIE.
