Take climbing, for example. A great part of Horizon Zero Dawn was its traversal, which saw Aloy clambering and scrabbling her way from one side of her world to the other. There were clever puzzles to solve and tricky places to reach, and it was up to the player to use their wits and skills to achieve their goals.
In this you very quickly realise that wits play no role in your achievement. There is a single solitary solution to each problem you face, and no guile is required to determine it. Tap the scan button and Aloy's Focus will helpfully highlight, in yellow, the one and only viable route up any cliff face.
This reduces bouldering to a tedious act of obligation, instead of the thrilling excursion it had been before. Aloy leaping and catching, just barely, one-handed on a hold no larger than her fingernails becomes annoying once you realise she had to head in this direction — that she was destined to barely make that jump, fated to catch herself at the very last second.
