See, the game I am playing...my home campaign....belongs to me in my mind. It might use IP that belongs to WotC (although it should be noted that the eminant Col Pladoh has put some of that into question, suggesting for instance that Mind Flayers were his IP, not transferred to TSR, and thus not transferred to WotC, and has declared that he made them Open) and to other companies, but that's not what I come to the table for. I don't say, "What's the best WotC IP I can use?" I say, "What's the best tool to make the best possible game (according to my own criteria)?"
I'm not sure that's an accurate quote? Can you provide a source?
I know that Gary's gone on record saying the OGL was a "really stupid idea", and that Wizards should have instead just licensed it out to major players rather that give a license that Wizards would have more control of to a half-dozen players.
The new OGL doesn't really restrict freedom. Honestly, most people, if they like the new D&D, will buy Wizards products and Third Party products that show creativity. I find the people who will refuse to buy because it's "not open" to be a vocal minority. I doubt it's gonna be a significant indent.
If they don't like the game, they have the benefit of the "more free" license.
And this will encourage third-parties to consider making brand new systems rather than copying or modifying the core D20 ruleset, it will make a "wider diversity" of systems which can help improve things. There's been a trend towards this already.
