Roleplaying Systems

[Superfluous Crow]

I think most of the campaigns i have played in were like that. I'm not sure whether that is a bad or a good thing ^^

Humorous Systems...

Discworld HERO games.

The system wasn't amusing, but the system certainly facilitated the fun style.

I have recently stumbled over HOL, which i mentioned in the tavern as well. I'm not sure exactly how playable it is, but the rules are goddamn funny. The entire rulebook (as well as the single supplement) are handwritten, and basically just make fun of games and humans.
Other than that, i have played "Everyone is John" where you play voices in a guy called John's head, and i have the rules for "killing puppies for satan" (self-explanatory) and Amerikkka (America divided into states of different extremisms, like Greater Seattle where the wannabe vampires live together with the environmentalists or California with their soccer mom cavalry). Haven't tried those though.

I used to be very enamored of Mutants&Masterminds because it gave me rules that then let me build my own races/creatures.  Now I'm finding that occasionally it doesn't have enough definition in some areas, is too rigid in others, and is maybe a bit more complicated that my favored system should be.  I kinda like Cartoon Action Hour: Season 2 for being more freeform in traits (while still having more fiddly bits than some), but it still feels like it's missing something.

I may just be growing away from systems into stories.

Had the chance to get some real playing/running 4e experience. I enjoyed it. Definitely easier to build adventures, too, even never having run it before.
