I am planning on writting a setting that combines the OGL Horror, Steam Punk and Wild West. The problem is that there does not seem to be a OGL Fantasy. Can I use Urban Arcana in its place? If so how much tweaking do I need?
I have not had the pleasure of looking at a OGL in a store, so I do not know exaclty what the system mechanics are. By looking at the previews of the the other OGL's the system seems to be a variation of d20 Modern. If the Pocket Players Manual is D&D is it built in the same d20 Modern method or is it simply D&D 3.5?
If it is D&D 3.5, how can that be worked into the other OGL's if it is a different system.
Of course I may be completly clueless about this because I have not actually seen the books.
