Sherpa is a role-playing game to play while hiking in the mountains, strolling in a park or along the beach, sitting by a pool or lake, rafting lazily down a river, waiting in a long line, as a passenger in a car, on a space station, etc. In other words, you can play Sherpa in situations in which another RPG would be awkward to run.
In Sherpa the GM uses a digital stopwatch instead of dice, and a character sheet fits on the back a business card.
Sherpa is a freeform game for experienced RPG gamemasters only. (Novice players are fine.)
Sherpa is complete in a 24 p. booklet, 8.5" by 5.5" (22x14 cm). It is intended for any genre and comes with 22 sample characters (including a complete ready-to-run fantasy party) and over 35 sample Professions - many more are possible.
