Didn't Cryptic still get licensing for the engine after they left which is partially why the Cryptic logo remained on the splash screen? And if not mistaken, Cryptic didn't sell the engine because they wanted to use it to build on for their future games which turned out to be Champions, Star Trek, and Neverwinter. So working out something with NCSoft, probably might have to work something out with Cryptic who went from Atari to PerfectWorld. Probably wouldn't be able to shut it down, but that could cause an added cost to run the game.
