A couple of posts ago, "anonymous" mentioned that he was developing a variant of the boardgame Settlers of Cataan featuring zombies from, well, Zombies!!!. I think that's a terrific idea, and I hope to play one day soon.
The idea made me wonder if other games could be modified to add shambling zombie action. Certainly the infamous Bruce Lee Game (BruceLeeGame!) would be simple enough to combine with Zombies; just add a few Zombie cards to the deck, add random zombie attacks on your dojos, and you're set. Really, how come no one's made a movie in which Bruce Lee fights off hordes of zombies? (They'd all line up and attack one at a time, of course.)
Zombie Monopoly might be fun. You could add random Zombie cards to Chance and Community Chest..."You have been eaten by a zombie. Do not pass go, do not collect $200 dollars." Zombies could spring up on your holdings, bringing down your property values. "Oh no! Just when I paid off my mortgage!"
I thought about zombie Scrabble, but couldn't come up with anything but bonus points for spelling out certain words, such as "brains," "zombies," "splatterpunk," "boomstick," etc.
Zombie charades would get pretty tedious after a couple of turns:
"Okay, one word..."
(Player tilts his head back, drools, extends one arm, shuffles around in random circles) "Urrrgh...ullllh...mulllghh..."
Zombie Axis and Allies might be cool. The game starts as normal, but after two turns, zombies spring up in a randomly chosen territory. They multiply very rapidly, and the focus of the game shifts from a world war between powers to a combined effort for survival, Nazis, Allies and Japanese working together to fight off the horde. Zombie Risk could work the same way.
In the world of computer games, someone should write a Zombie Outbreak mod for Civilization. I would think it would be deceptively simple...just replace roaming barbarians with zombies, but have them multiply faster. And if they win combat with your unit, the unit isn't just destroyed - it's turned into a zombie too!
