A roleplaying game set in outer space, where everything is nutty and zany. The system is called "Token Effort" and it works by giving all players (and the GM) a number of tokens with which to advance the plot elements they want to see happen.
You can use tokens to edit the plot. 'Oh I happen to find an abandoned ship filled with food, weapons and survival gear.' (Don't laugh, it worked for Robinson Crusoe.) 'Just before he chops off her head, he realizes that his shoe's untied and puts down the ceremonial decapitation laser in order to tie it.'? 'My character used to play a video game whose controls were modeled exactly on the XB-55 Starfighter, so it's as if she knows how to fly it.'? 'I find a pack of gum in my pocket.' Small effects and large, they can all be created through the use of tokens.
