The first 2 games actually had GFWL, which was later removed. Unlike Gearbox who re-released Bulletstorm at a massively inflated price for the GFWL removal, WB/Rocksteady just upgraded all existing customers to the GOTY versions in an update, which was nice.

Knight had Denuvo, as I understand, but I didn't get around to that game until long after it was removed and long after all the issues were fixed with Iron Galaxy's shitshow of a port.
