The Guy Game
Platform: PlayStation 2, Xbox, PC
Part pornography, part trivia challenge, The Guy Game offers up videos of topless Girls Gone Wild rejects in exchange for correct answers to obscure questions. While it's certainly not the most mentally taxing trivia game on the market, it certainly provides the right motivation. That being said, if you're thinking of hunting down a copy of this perverted gem, you should probably stop lest you enjoy being listed on the Sex Offender Registry Board.
Four months after the game's release the developers at Top Heavy Studios were saddled with a lawsuit for including video of an underage girl who had lied about her birthdate at the time of filming. The game was pulled from shelves and is currently banned across the United States because of its child pornography content.
