I used to love Mouse Trap from Milton Bradley. Well, I liked setting off the trap. Putting the game together was pretty annoying, a lot of work for two seconds worth of enjoyment. Even the actual game play, when I bothered, was just to have fun watching the trap go off. In fact, this animated gif totally replaces the game:
I can just watch it go off over and over without having to play a boring game, set up anything, and so on. It’s perfect.
