mshea said:One of the things I always considered was that OGL was a simple way of licensing something that people may have already been able to do.
There are only two laws that protect this sort of stuff: copyright and trademark law.
As long as you don't directly reprint material from a book, you can talk all about it, right?
Why couldn't someone make a compatible product without ever even talking about the original?
Considering that the core of d20 is used in 4e, couldn't you just base your material off of the original d20 but using more 4e-style stuff?
As long as I don't reprint material falling under standard copyright law, can't I write something close?
I don't think you can copyright "roll 1d20, add a modifier, match it against a difficulty check".
Maybe I'm wrong. Can someone explain the laws of this to me?
I think this is true. Fact is that it does not make any business sense to do such a thing if it is not licensed. People will not buy something evolutionary from you because they feel the big guy offers a better long term support which is a better condition regarding the need of evolution.
So now you better have to provide something revolutionary than evolutionary. And this is where the hobby mostly needs to focus now IMO.
