I'm about 80% committed to making Liber Zero an OGL game with a liberal complimentary license for some of the Product Identity portion, as described elsewhere. But I'm still 20% toying with the idea of going completely Creative Commons on the summary document, ditching the OGL completely. This is why not too long ago I asked about recent RPGs that were very close to D&D but not OGL; I figure if Liber Zero has some distinct (but work-alike) mechanics, procedures and tables, and doesn't copy terminology any more than other non-OGL games that didn't get sued, it would probably work. I'm just not certain if it would be worth it.
One small example: the names of the six primary abilities. Some games have the same six abilities with completely different names, while others only change some of the names; some games add one or two abilities, some replace one (usually Wisdom,) some drop one or more.
My guess is that I could definitely keep Strength, Intelligence, and Dexterity, since they are used in The Fantasy Trip, GURPS, and Runequest/BRP, and I could probably get away with keeping the names Constitution and Charisma, since they are shared with BRP. I have three basic ideas:
- Rename Wisdom to Sense and define it as "ability to sense when something is wrong -- moral sense, common sense, and danger sense combined." It's still the prime requisite for Clerics.
- Add an ability called Wealth, rolled the same way. 10 x Wealth equals starting gold. Add some other minor uses for the Wealth ability.
- Add an ability called Loyalty, but only for hirelings.
