Ragnarok caused other developers to delay their games. According to Tim Gettys of Kinda Funny, developers and publishers may have been “scared” by God of War Ragnarok. Gettys noted that he had business calls with several people who were “shocked” by the game.
He claims the developers/publishers were getting out of Kratos’ way and “removing” things. He doesn’t go into details, but says that everyone was looking to make room for the next God of War. Considering he could be a strong contender for Game of the Year to honor his predecessor, it’s understandable that some developers want to keep their distance from him.
