In 1982 there was actually a video game called "Outhouse". It was made for the TRS-80 and basically was a game about stopping people from using up all your toilet paper. It was the dawn of the video game revolution, the prospects were limitless, the future full of possibilites.... and they make a video game about preserving toilet paper?
This sounds bad, but I would have to say it's not the worst video game of all time. That distinction goes to the E.T. game for Atari. No game was more hotly anticipated, and no game was a bigger disappointment. Outhouse was certainly a lousy game, but at least you knew what you getting into when you bought it.
Without any hesitation, the most politcally incorrect video game of all time has to be Custer's Revenge. The object is to have General Custer exact his revenge by literally raping a Sioux Indian girl. This is beyond being un-PC, beyond offensive, beyond despicable. I stand in complete amazement that this ever existed.
