GSL, D20, OGL, D20-GSL, OMG

The open gaming license decision was finally announced yesterday by Wizards of the Coast. There weren't many details but, "The effective start date for sales of D&D 4E GSL publications will be October 1, 2008." This gives WOTC four months of lead time to impress customers with their products, and they'll have quite a line up with 12 books published by 10/1. The GSL is the equivalent of the 3.x D20 license. Wizards is also working on an OGL-like license that will be called D20-GSL, for games that use the D20 mechanics but aren't D&D. Confused yet?

None of these licenses are revocable, so they'll be with us forever. We'll have:

Product	3.x	4.x	Example
D&D Accessories	D20	GSL	Adventures, Accessory
Spinoff Games	OGL	D20-GSL	Conan, Pathfinder
