Unlike the leaked OGL 1.1, the proposed OGL 1.2 contained "no royalty payment, no financial reporting, no license-back, no registration, no distinction between commercial and non-commercial". The proposed OGL 1.2 would have de-authorize the OGL1.0a; it would also be "irrevocable, although there's still a severability clause should a part of the license is held to be unenforceable or invalid".

It "was considered by WOTC's managers as a huge success due to the large movement of adoption it created among publishers". They also highlighted that the "success was amplified by the rise of electronic publishing". Mike Whelan and Bob Tarantino, for Law Insider in 2021, commented that "the scope of the Open Game License is incredibly broad. The license is perpetual, worldwide, royalty-free, and not exclusive.
