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

Execution · Practiced Mastery
Open-zone Metro entry trading tunnels for a cross-Russia survival journey.

Optimization · Practiced Mastery
Lara raids Siberian tombs in a stealth-action adventure heavy on puzzles.
Metro Exodus leans Execution (Practiced Mastery); Rise of the Tomb Raider 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.
Metro Exodus
open-zone gunplay and stealth takedowns
Rise of the Tomb Raider
Bow aim, stealth timing, and platforming sequences.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Metro Exodus
human and mutant AI is mappable
Rise of the Tomb Raider
Guards follow predictable patrol scripts.
Metro Exodus leans a little harder on variance, though the gap is small.
Metro Exodus
weather and patrols add mild uncertainty
Rise of the Tomb Raider
Tomb unknowns dissolve after one visit.
Rise of the Tomb Raider leans a little harder on optimization, though the gap is small.
Metro Exodus
crafting, scavenging, and approach planning
Rise of the Tomb Raider
Tomb puzzles, crafting, and collectible routing are solvable.
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.
