Where's Waldo & Family Feud for the SNES are both awful and super fun to play. I remember loving Brutal: Paws of Fury when I was a kid, I played it recently and.... no. Battletoads/Double Dragon is always fun, as are most Battletoads games since they're all unnecessarily difficult. There's also some SNES game called Harley's Humongous Adventure or something that I fucking despise.. I hate Cool Spot, too.
In Krusty's Super Fun House, for some dumb ass reason, you can turn the background music off. If you make Krusty just stand there and do nothing with the music off, it turns into the creepiest game of all time.
