If you love Prime time Adventures, you will also love Fiasco. I have never laughed so much playing an RPG.
Fiasco can be played in a couple of hours with zero prep making it a fantastic option if a player doesn't show up for a regular game or you are strapped for time. It is also a great option for introducing actors and other theatre folk to role playing as everything is framed in scenes and the game is built to feel like a movie.
There are playsets (kinda like settings) for everything from gangsters in London to American suburban tales.
If you have players that are still stuck in "old-school-loot-and-kill-my-character-is-really-me" mode then this game can really help them evolve to more of a collaborative story building style of play.
I believe Fiasco belongs in every role player's kit bag. It's that good.
