The whole point of wiki-ing stuff -- and this includes crafty-games.com -- is to put it in an easily accessible format for people to use. (We should probably ignore that a really good percentage of stuff on the Crafty site is people playing with properties that arguably they don't have the right too when they decide they want to adapt a particular setting such as Star Wars or Mass Effect to Mastercraft)

The whole point of the OGL is allowing folks to use pre-existing mechanics to build their own stuff by releasing that pre-existing mechanic out into the wild, on the proviso that anything based on that mechanic is also similarly set free. By using any OGL mechanic that is not explicitly Product Identity, you've already been granted and in turn grant others the right to use and share it provided the creator of the stuff you didn't make yourself is attributed.

Virtually everything on LTI is based on the OGL anyway -- Mistborn has been pretty studiously ignored beyond a half-hearted suggestion at Star Wars -- which as a result means they too are OGL.

The New Pie is built upon the framework of the OGL mechanics -- attributes provide modifiers to checks, skills are gained in ranks, classes have levels, there are 3 types of save, etc etc etc.
