How does the whole OGL/D20 license thing work if WotC changes to 4E? Can companies like Green Ronin, Mongoose etc. still produce OGL or D20 books based on the 3.5 or 4E rules? Or is this coming edition change going to kill them?
The OGL genie is out of the bottle. So if your game is only OGL, and not d20, (like Mutants & Masterminds or Castles & Crusades, or even OSRIC, for that matter), a change to 4E will not affect your system. However, if your game is d20, you're operating under tighter restrictions. You can't describe the process for creating a character, you can't describe a process for applying the effects of experience to a character, can't include miniatures, etc. Also, while the OGL explicitly states that you don't have to use the most updated version of the license, the d20 license says that "Wizards of the Coast may issue updates and/or revisions to this License without prior notice. You will conform in all respects to the updated or revised terms of this License. Subsequent versions of this License will bear a different version number."
That said, I would imagine that it's possible to create a non-d20, but OGL rules set that mimics d20 in almost all respects (although it couldn't call itself "d20"). Game rules/algorithms are not subject to copyright law, so as long as you don't infringe on any trademarks, use original or licensed (i.e. OGL) descriptions of game rules/algorithms to avoid copyright infringement, and abide by the terms of any license you do take advantage of (e.g. OGL, again), you wouldn't be breaking any laws.
Take a look at what was done with
OSRIC. It was created using the OGL. Something similar could be done with a different edition in mind, if the 3E core rules were no longer readily available.
Frankly, I don't like the direction WotC is taking the game either, and there are several variants of the system that I like better....AE, AGOT, and possibly True20 among others. And I'm reading Conan, and liking what I've seen so far. Can those games continue selling?
If they're OGL-based, but not d20 (like True20, for example), then there's no problem at all. If they're d20 licensed products, then it's a stickier issue.
