Well, actually, for me, it doesn't really matter cos on Boxing Day I just play with all the new games I got
Snake Eyes (like Damien said) would be a good one though! Like you roll the die, if you get 2 - 6, nothing happens, if you get 7 - 11 you get a belief boost, and if you get 12, you get an instant flee of one mortal?
Or how about 'Gambler's Luck' that is pure random if it's a belief, insanity or terror strike!
Or 'Roulette Table' that spins the room around (or so the mortals think it does)
Or 'Boogeyman's Lair' that makes the room go dark with eery music!
