i live in the ass end of nowhere, so i generally play with whoever accepts its, and my current group is, to put it bluntly, dumber than a sack of dead rats. i could only muster two guys up (yaaaaaay), and one is a coldhearted homicidal motherfucker, and the other is really friggin silly. this might not SOUND bad for a usual hacky-slashy DND game, but we tried Call of Cthulhu once. i was running an adaptation of "Cult of the Reptile God" (great adventure that), whcih ran under CoC rules. so, first thing they do is go into the golden grain inn and loudly say "So, i hear you are in a Cult". and then they look at me, completely baffled, when all of the cult motherfuckers in the bar leap up and attack them. they survive (barely, one of them crit'd and destroyed the phone before a call for cops was made), and then follow the bartender, who they ran away from, home a month later, BEAT HIM TO DEATH, and bury him in a shallow grave after stealing all of his shit. they are then baffled at the fact that his family missed him and put in a missing persons report, which leads to them being arrested and given the death sentence for at least 6 murders according to witnesses. other highlights of this game include dropping a fuckload of acid, and one knocking the other out with a golf club, and then being surprised when this caused BRAIN DAMAGE! (he crit'd, its a wonder the damage didnt kill him). jesus christ.
this story of mine sums up my current set of players for tabletop games.
