They're clearly making more of an effort with Rage than they did with previous engines. They were spoiled to a degree by how eagerly 3rd-parties licensed the Doom, Quake, and Quake II engines. Id developed a nasty reputation for dumping code on licensees with little support. In fact, one of the main ways Epic stole the licensed engine market from them was by providing much more aggressive marketing and support. Id's attitude was always "if we build it, they will come".
