Eurogamer has word from id Software's Todd Hollenshead that they will not be licensing out the Tech 5 engine being used for RAGE to third parties. At one point the plan was to license the engine, but after id was acquired by Zenimax it was decided that the engine would be reserved for id's and Bethesda's internal development. "It's going to be used within ZeniMax, so we're not going to license it to external parties," Hollenshead told Eurogamer at QuakeCon today. "It's like, look, this is a competitive advantage and we want to keep it within games we publish - not necessarily exclusively to id or id titles, but if you're going to make a game with id Tech 5 then it needs to be published by Bethesda, which I think is a fair thing."
