Now go to your local comic book store or gaming store...and get a game called "Cthulhu Dice"....
Everyone gets 3 "sanity tokens"...you chose a player, roll the dice. Depending what comes up on this big D12 (12 sided die)....the chosen player gives a sanity token to Cthulhu, to the player rolling, nothing, Cthulhu gives them a sanity token, or EVERYONE gives a sanity token to Cthulhu. After that the "attacked" player gets to roll in retaliation. Then the next player choses his victim.
When you lose all your "Sanity Tokens" you are now a minion of Cthulhu (and insane), and cannot be attacked, but still get to attack. The only way to get a sanity token after you have none is for Cthulhu to give you one.
It's great fun, and a VERY fast game. Goal is to be the only "Sane" survivor. We had several that ended with no winner at all (2 people, 1 token each, and everyone gives a sanity token to Cthulhu).
And after typing this, Firefox's spell check catches that Cthulhu should be capitalized......kinda creepy...
