You play semi-famous science fiction authors living in late 196Os California. The game's inspired by the lives of people like Philip K. Dick and L. Ron Hubbard. Left Coast is a game for 2-4 players that involves some co-GMing. It's designed to promote a relaxed exploration of character and setting, with the occasional pretentious flash of meta-narratives, post-modernism, and nuttiness.
Play is divided into chapters or short stories, and every author sets a goal that they're trying to achieve during that chapter. You can probably play a self-contained short story of Left Coast in about 2 hours, with the option to continue the game for longer (probably between 3 to 6 sessions).
