Today, Steve Jackson Games released a bunch of GURPS PDFs on OneBookShelf/DriveThruRPG/RPGNow. It's a far cry from the much larger library of PDFs they are selling on their own store. Prior to today, Steve Jackson Games sold PDFs exclusively on their own store, making them one of only two moderate-sized RPG publishers not selling through OBS. There is now only one medium-sized RPG publisher who refuses to sell their PDFs through DrivethruRPG: Paizo.
