That’s the difference between Fox and Illfonic - they are respectful to the original movies and are not adding any politics or propaganda to their story, so as you have mentioned, even Arnie was interested - that is first time he is back since original Predator.
There is something about Arnie and Sean recordings that gave me that chill, same one when I first watched Predator and Predator 2. The game may not be perfect, but sure as hell they know what they are doing with their story telling.
Because of that I very much doubt we are ever going to see godzilla Predators, predator killer suits or side quests for pred to find and kill a child with autism.
