Craftwork

Publisher's blurb:

Do you ever get tired of the same old character generation? Give CraftWork a try to quickly develop diverse and memorable player and non-player characters through flexible crafts instead of system-prescribed classes. Inside you'll find:

Eight classic character paths, or “crafts,” such as MageCraft, ThiefCraft, Stagecraft, all of which interweave as broadly as you can imagine!
Crafts, skills, and abilities laid out so they can be easily randomized using a standard set of dice.
Procedures to evolve unique PCs and NPCs with intriguing skill-sets that work alongside multiple systems.

Favoring description and common mechanics, CraftWork references many RPG touchstones and is playful, hackable, and adaptable.
