Just don't use the OGL. If Chaosium says publishers are lining up to use the BRP "OLG", then by all means let them make their games. If there is something better for everybody else, just use that. Do you really even want to use the BRP logo anymore after all this? That's the only real perk of this so-called olg, and it doesn't mean much to me. I was planning on using the OGL, but now I think I would be better off just making my own system or taking advantage of actual ogls. I don't think this move was intended for us, it is geared toward making sure something like OpenCthulhu never happens again. Its purpose is not for you to make a game, its purpose is to tell you "hey, we created (or simply own) ect. Don't pretend you have any legal right to use ect the way we do." We don't, and their move makes total sense, and they are telling us what we can do with BRP as well; which is nice. I don't like that they are disguising the fact, but if others will use this license to make something awesome, great for them:)
I just won't be using it myself.
