21 What is the narrowest genre RPG you have ever played? How was it?
Again, that would probably be Kobolds Ate My Baby. You can play a kobold, a kobold with a wooden spoon, or if you're lucky a kobold with a sharp stick. You can get killed fighting chickens, village children with sticks can pound you to death, and you have one mission and one mission only... King Torg (All Hail King Torg!) wants to eat that baby!
Now, this is probably not the sort of game you build massive campaigns around. But if you don't have a quorum in your gaming group one night, or the DM has the flu or whatever, it's a nice little game to whip out and play. It doesn't take a whole lot of prep, I would think (having only been a player, not the GM). Char-gen is minimal and random and really in the big picture not that important. Like I said, no matter how lucky you get with the random rolls, you're likely going to die quickly anyway.
