Beautifully presented and includes ASL and BSL guides. While I haven't had chance to play much, it is simple system, openly encouraging creativity and cooperation. The reliance on player imagination over hard-set rules may be difficult for some people to get used to, but shouldn't put people off (some players may need a little prodding, especially if they're primarily used to combat-heavy campaigns).

The guides to sign language are well formatted and easy to understand, and quite frankly makes this worth picking up even if you don't get chance to play. It is a useful resource even away from the table.
