Not at all. His logic makes no sense considering Krato's behavior in-game. It's just another excuse by blind fanboys trying hard to defend an indefensible choice made by Santa Monica due to their lack of technical expertise on combining jump with their choice of camera.
@funcrusher Kratos doesn't want Atreus to know he is a God, but at the same time Kratos has absolute no reservations when it comes to demonstrating his godlike physical prowess in front of Atreus throughout the entire game. He constantly beats down monsters 10x his size, lifts car sized boulders like they weigh next to nothing, and yet somehow he singles out "jumping vertically" as the one physical action to avoid in order not to blow his God cover? Neither your argument, nor Santa Monica's choice on this make any sense in-game.
What about forcing himself to jump on top of a 12' platform in order to progress through the story? He hops on and off 12' moving trolls and ogres on the regular, but when it comes to stationary platforms it's a big no-no?
By your logic, the first part of GOW should have been a survival horror game designed around stealth and avoiding enemies, because if jumping is a big no-no, if jumping up 12' would blow his godly cover, then so would a million other things he does in battle. In terms of feats Kratos demonstrates in front of his kid, a 12' vertical jump would be one of the least impressive.
There are a million examples of Kratos demonstrating far more impressive physical feats in front of Atreus than a 12' vertical jump, pre-God review. It's one thing to justify him not wanting to jump for miles straight on top of the mountain and bypass the game entirely, and a whole other to justify zero vertical jump using "Kratos doesn't want to show his godly powers in front of Atreus", just so the studio can shove generic platform puzzles in your face, when Kratos' behavior throughout the game directly contradicts that. It's lazy and completely inconsistent based on in-game logic.
