Ask COD developer activision if they like their toilet paper made with African mohagony or Emargo'd African Blackwoods for the angel touch on their brown eye. As long as money rules you will continue to get cookie cutter sequels that are stealing taking design philosophies from witcher 3.
That trailer looks interesting from a story standpoint and fighting mythological creatures is a bit of a twist for the Assassins creed series. One I'm a bit disappointed about. Superior alien tech... ok sure.. but monsters... really? I guess it was only a matter of time.
