Oh, It's THAT Sort of Game - Games That Didn't Look Nasty At First
New South Wales
Buster Keaton from 'Go West'
Often the rules of a game don't tell you much about how it's played. Some games may seem like a cooperative building game, and even be played as such by some groups, but other groups will interpret them as an uncooperative blocking game. Please list games where the rules just tell you what the rules are, and then when you play you discover that the game is much nastier than you thought.
