My thinking is simple. They are planning a sandbox MMO. Has there been a sandbox MMO more popular than Star Wars Galaxies? I don't believe so. SWG was badly mismanaged, but the MMO market has shown sandbox style MMOs to be drastically less popular than them park style. For those who aren't familiar w/the terms, sandbox is an open world, not really quest driven, more things up to the players to make their own fun. Theme park refers to an MMO that is highly quest driven, lots of planned activities built into the game, etc. World of Warcraft, Star Wars: The Old Republic, Everquest, those are all theme park MMOs. Star Wars Galaxies is the best example that I'm the most familiar with as I played that for a few years.
I wish them luck, but I don't have much in the way of expectations. This has nothing to do w/my opinions on Pathfinder as an RPG itself.
