To make a spoof commercial about a fake board game, all you need is a basic idea and a little artwork; the jokes and bad acting write themselves.
Mush Mouth - Stupid game ideas like this actually exist in the recycling bins of game publishers.
Number Scrabble - Demonstrating that obvious adaptation ideas don't always work. Letter card games that play like rummy are no better.
Smack the Lion - Those wacky Japanese.
Grand Theft Auto: The Board Game - Applying real world violence to a board game is a little too obvious.
Communist Monopoly - These guys had a similar idea a decade earlier than GTA, and it still seems fairly old.
NAMBLA - This one is probably offensive to most people, as is the organization.
25 Years to Life
Chess For Girls - One of several board game commercials done by Saturday Night Live. Actually makes a decent point.
Ball Buster - This was a real game, believe it or not. I don't think the commercial is a spoof.
To make up for the previous entry which was a real game, you can view Blackout. It's a little too racy for my blog.
