After endlessly shitting on linear games, Jack want this semi-open game to be more linear.
That's not entirely true. Jack said that he had a problem with the pacing of the game. Rich said that was because Jack foolishly went out of his way to do every single sidequest as soon as it became available. Jack said that he felt obligated to to them. Rich asked why Jack didn't just do them later, at a time when he felt like doing them, and Jack was like "I didn't know you could do that" and Rich gave him shit for that being his own damn fault.
Jack also wanted the game to be somewhat
less linear, because as a dad and the player, he was actively fighting Kratos to try and steer him into becoming a better dad, while Rich didn't give a shit and was 100% actively onboard with turning the kid into a murder-machine, and Jack would've liked it if the game had a "dad meter" (so Jack and Rich could both be satisfied).
Then Jack suggested that
a story rich game needs controls on it's pacing, otherwise it messes with the story, and spitballed perhaps having a narrower focus on the goal, followed by an unlock at the end where you run around with your kid and do a massive victory lap.
The review ended with Rich (the guy who hates story-based games with a passion) calling it the second-best game on PS4, and Jack saying he had a bad experience, and cautioning people not to power through all the sidequests like he did. Seems like a valuable set of opinions to me.
