I've played
Munchkin.
The deck belonged to DIO, and I can say it is a fun card game, but it's been quite a while since I played it so I can't say much more.
Another card game DIO has, which sounds horrifying, but is fun, is
Kittens In A Blender, where you try to save your kittens from being blended.
DES of course ruined the game by gathering up all the kitten cards and running away with them saying "I'll save you Georges!"
