head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

Execution · Practiced Mastery
A glitch-themed metroidvania built on exploration routing and pattern bosses.

Optimization · Practiced Mastery
A minimalist action adventure about toppling sixteen colossal puzzle-bosses.
Axiom Verge leans Execution (Practiced Mastery); Shadow of the Colossus leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Axiom Verge
Boss dodging and platforming reward precision.
Shadow of the Colossus
Climbing, grip management, and sword timing on moving giants.
Shadow of the Colossus leans a little harder on reads, though the gap is small.
Axiom Verge
No adaptive opposition.
Shadow of the Colossus
Colossi follow fixed behavior patterns.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Axiom Verge
World fixed and explorable.
Shadow of the Colossus
Encounters play out nearly identically each attempt.
Shadow of the Colossus leans a little harder on optimization, though the gap is small.
Axiom Verge
Item routing and sequence breaks deeply learnable.
Shadow of the Colossus
Each colossus is a solvable climbing puzzle.
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
