Eric Bischoff wrote the following on Twitter regarding Hulk Hogan's inclusion in WWE 2K14:
Yes, it's true WWE is utilizing trademarks they already own but there's more to it. There is an agreement to use Hogan and his likeness in the video game. Hogan gets royalty checks from WWE when his name and likeness are used. He would not be included without a deal and there is very much a monetary component to the agreement.
The Ultimate Warrior has a deal with 2KSports where he is used to help promote the game. To insinuate the aforementioned names have NOTHING to do with a game that will sell in the millions is fairly asinine. However, Eric will be Eric and we do love him.
