I just got a copy of the No Press Anthology, and boy, it is one cool book of short roleplaying games.
Just from skimming the games, it looks like Snowball would be a cool off the cuff narrativist RPG engine, WTF a much more silly one, Pretender, Pagoda, and The Agency would be good high adventure high coolness short narrativist games, Cell Gamma and Discernment, would be good conceptual weird-out games.
Oh, and Over the Bar is kind of a joke, though I guess you could play it. Don’t worry, it doesn’t take up much of the page count. :)
Highly recommended. Hope to play some of these sometime.
