This is a free ‘lite version’ of Tibet the RPG, available for download in Adobe Acrobat (pdf) format.
It’s 169 pages and is a complete game, with skills, equipment, a ton of setting information and everything else you’ll need to create characters or GM the game.
However, the Monastic Edition only comes with the character creation options and setting info pertinent to monk characters (four out of the 25 character classes available in the full version).
The Tibet Monastic Edition is can be downloaded free from DriveThuRPG.
