enrious said:I asked that because the PCGen folks said that because they did not follow the OGL, they were not bound by it, only standard copyright laws.
I'm not a lawyer (and Clark is, though Clark's legal opinion seems to match up pretty well with both my understanding of what the law is, and what I think is 'right'), but I think that the PCGen folks are (or at least were) operating under some serious misunderstandings regarding copyright law.
Major misunderstanding 1: "Game mechanics can't be copyrighted, so if we stick to the numbers, we're okay." This hasn't been tested in court one way or another to my knowledge, but I strongly suspsect it's not true. Yes, a lot of people seem to believe this, but I'm not sure where it comes from.
Major misunderstanding 2: "We're not using the OGL, so we're not bound by it." Clark has already explained why this is not the case. By distributing OGC, you're implicitly agreeing to the OGL.
Major misunderstanding 3: "We're an open source/freeware fan project. We're not making on money off of this, so we're okay." Err, no. Copyright violations are just as illegal whether you are making money or not. If you aren't making money, you may be liable for less in damages if you're sued, but that's about all being fee/open source software gets you.
