While not a video game, there is one hideous PC game that sticks out in my mind: Gadget. It was the most worthless game I've ever seen. Had the controls not been so difficult to figure out I could have easily finished the game in 15 minutes. No story, no puzzles, hardly any dialogue, no music, no point to playing it whatsoever. The only content it even had were a bunch of somewhat nicely rendered (still-frame) graphics. That game still gives me nightmares....
