Is Disney Trying to Buy NEXON?

That doesn't make a lick of sense. If they were going to go to all that trouble, they'd just create an entirely new IP, not buy an existing one and sink a lot of time, effort, and money into it to completely change it, knowing that the existing fanbase may reject the whole thing and leave completely.

If Disney were to become involved, it would only be to ADD things to the game, not remove what we have and put Disney IP in its place. They would potentially add Disney bosses, it's true, but they would put them in new areas. They wouldn't overwrite Horntail with Maleficent, Pianus with Ursula, Papulatus with Hades.

But look at how Coke's partnership with Nexon paid off with Coke Town. In kMS, they didn't remove all monsters in Maple World and replace them with Coke themed alternatives. Just as they wouldn't replace existing Maple World monsters with Disney analogues if Disney were to be involved in the project.

Epic win.

Couldn't have explained it better.
