What's the primary draw of Unity? Valve, Epic, and id learned a long time ago that the real money to be made is in engine licensing rather than actually making games (unless the goal of said game is to show off your engine).
What is it that Unity has that these companies have been so unable to replicate? Surely they don't want another player in the scene to compete with their engines.
