KNAVE is a skeleton ruleset that combines flexibility with a clean numerological system. It avoids the pitfalls of number scaling so commonly found in most tabletop rpg games and motivates players to find creative solutions to various situations without recurring to their "skills". It is quick, easy to understand and prêt-à-porter. Characters can be done in a matter of minutes, which is perfect for one shots and short sessions, so you can gather a large group for a session and be ready to play in short amount of time.
This is a game for those who look for a healthy dose of simplicity in a D20 system and have no problems creating house ruling for any vaccuum found in effects or descriptions.
This is also a game for those who want to develop an RPG game with the familiar D20 system, but need a solid structure from where to work on.
