RangerWickett said:I know that the OGL requires you to have at least a certain percentage of new material in the product (5%, I believe).
The d20 System Trademark License requires the 5%.
The OGL does not.
If you use the d20 logo on the product (and frankly, I don't know what it would gain you in the case of P&M, so I wouldn't advise it) then you would have to include 5% new material.
