Lionhead’s Master Plan on CheckOut.Com alludes to the recent "engine wars" dispute, describing the method of game production at Peter Molyneux's Lionhead Studios as a third alternative to creating or licensing game engine technology, making the analogy to the old "studio system" of movie production. The method actually sounds like a more full-featured version of a traditional licensing agreement, but maybe there are unmentioned provisions for sleeping with studio executives or something.
