Nothing gives someone more dread than a Jenga tower with a spire balancing on one block and thats why this rpg lends itself so well to the horror genre. Not only are you terrified of the story going on (hopefully) but that already instilling dread is now sitting there in front of you waiting to topple.

This system would be great for any Call of Cthulhu game providing you can find a Jenga pile for each player...
