While we don't play Pathfinder these days, I backed it out of nostalgia for Paizo and all the former Greyhawk folks who worked there. Plus, I'm interested in how they introduced ancestry as a replacement for races/species and generally evolved the 3.x rules base.
The humble bundle also includes a bunch of Paizo's Flipmats as PDFs, which can easily be turned into online battle maps. Given how much we're playing online, that's a good resource to have
And there's a bunch of other content too (including the PDF of the Bestiary ... and I do love my monster books )
