Jason Buhlman over on Paizo's board, unfortunately don't remember the thread, stated that if they do another RPG (not Pathfinder) they wouldn't follow the OGL design.
Was this with respect to a fantasy or a non-fantasy rpg?
I wouldn't be surprised if after a few years of a dozen or two released hardcover splatbooks for Pathfinder, the ruleset becomes very unwieldy and messy. By that time, the hardcover splatbook product line will probably be beyond its point of diminishing returns anyways. This year, there's already four new hardcover Pathfinder splatbooks scheduled for release in 2010. They haven't officially mentioned anything about 2011 so far, but I wouldn't be surprised if they released another Bestiary, another "Advanced Player's Guide", and another Golarion setting book at minimum during 2011.
Perhaps right now they're already working on a new ruleset for a hypothetical second edition of Pathfinder, free from the structure of the straitjacket of the 3.5E/OGL mechanics. If I had to guess for a starting point, it will probably still have most of the traditional D&D fantasy tropes such as:
- rolling a d20 to attack, and rolling for damage after a hit
- classes: fighter, cleric, wizard, rogue, etc ...
- races: elves, dwarves, halflings, gnomes, humans, etc ...
- monsters: kobolds, goblins, orcs, etc ...
- Vancian magic
Too much deviation away from traditional D&D fantasy tropes may possibly drive away too many of their existing customers, for a hypothetical 2E Pathfinder rpg.
He stated there were a lot of ideas they couldn't go with for Pathfinder because it would have change the game too much and they wanted to keep their 3.5 followers.
That was probably "marketing" or "PR" speak for the most part by Buhlman and others at Paizo.
At that time (ie. 2007-2008), 3.5/OGL was probably the safest option to pursue. If they had made a completely different ruleset for Pathfinder at the time, most likely it would have ended up as another "fantasy heartbreaker". 3.5 followers may not have latched onto it.
I'm hoping they eventually create another system if only to see what kind of ideas they had brewing in their minds.
Same here.
