Personally, it seems that true OPEN GAME CONTENT is DEAD. Unless I am mistaken, it appears that in order for any 3rd party publisher to publish any content (I am not talking about IP) of another 3rd party publisher, they must seek permission.
I am fine with this, since most of our rules are 100% - but we have supplemented if we wanted the same game effect rather than making our rules for them.
If I am correct in this assumption, you might see several "look-alike" monsters or powers or feats, etc. from 3rd party publishers which might confuse consumers. On the otherhand, consumers might also benefit by having more orginal content, thus getting more bang for their buck.
Either, I definately think the
GSL will cause a reduction of smaller 3rd party publishers.
I am glad however to be rid of that bulky
OGL and OGC section of a product. The OGC especially.
