head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Practiced Mastery
Lara's reboot blending cover shooting, climbing, and survival cinema.

Execution · Practiced Mastery
The acclaimed cinematic action sequel famous for its train and collapsing-building set pieces.
Tomb Raider (2013) leans Execution (Practiced Mastery); Uncharted 2: Among Thieves leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Tomb Raider (2013)
Bow aim, QTEs, and platforming timing matter.
Uncharted 2: Among Thieves
Set-piece gunplay and traversal under fire
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Tomb Raider (2013)
Scripted enemy waves, no adaptation.
Uncharted 2: Among Thieves
Campaign AI is scripted; MP adds a trace
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Tomb Raider (2013)
Minimal randomness in encounters.
Uncharted 2: Among Thieves
Authored spectacle, nothing hidden
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Tomb Raider (2013)
Weapon upgrades and skill picks straightforward.
Uncharted 2: Among Thieves
Encounter knowledge trivializes replays
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.
