The relevant text in the GSL (clause 4.1) states that "Licensee will not define, redefine, or alter the definition of any 4E Reference in a Licensed Product. Without limiting the foregoing, Licensee may create original material that adds to the applicability of a 4E Reference, so long as this original material complies with the preceding sentence."Hypersmurf said:Right. If you change the Orc Berserker's weapon, you can say that he has the melee attack Falchion, and that it is +6, 1d8+4, and that he has the power Warrior's Surge... but you still can't say what Warrior's Surge does. If all you've changed is the weapon, you probably can't list the Orc Berserker's Intelligence or his Speed, since those can be found in the D&D 4E Monster Manual.
What I'm also not sure about:
... you can add functions to 4E References as long as, in doing so, you don’t redefine that 4E Reference.
So you can certainly add the Battleaxe attack to the Orc Berserker, but I don't know if you can take away the Greataxe attack, since that would involve redefining the 4E Reference...
Probably the easiest way to do it would be along the lines of "The Orc Chopper has the same statistics as an Orc Beserker except that, in place of a Great Axe attack, he attacks with a Falchion: +6, 1d8+4."
The best way to do this would probably be as someone suggested upthread, namely, use names that WoTC cannot use without violating your copyright or infringing your trademark.Talath said:the GSL is restrictive, but honestly, do you think WotC would approve a license that forced 3pps to modify their published works if WotC happens to use something similar, or similarly named?
I'm not an IP lawyer, but I would be surprised if the US laws of fair use permitted the reproduction or derivation of a work for commercial purposes (other than perhaps in the context of criticism, satire or review).argash said:I'd be interested to hear the opinion of an IP lawyer to determine what a publisher could do on their own without the GSL under the guise of current IP laws as far as fair use.
I think that would likely be quite difficult (but not necessarily impossible). It would depend upon the relevant US law pertaining to "derivative works" - the work you are talking about would be, after all, highly derivative in a certain obvious if non-technical sense - and also upon the extent to which the work might be taken to involve trademark infringements or some other sort of passing off.resistor said:So where would that leave OSRIC 4e? It should, in theory, be possible to create a ruleset that implements the same underlying rules, but does so without duplicating any of the actual expression of said rules from 4e.
In this respect OSRIC has the significant advantage of using the OGL and, thereby, the d20 SRD. Its useage of WoTC intellectual property is therefore licenced.
