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

Execution · Practiced Mastery
Tests cautious route planning and scavenged-resource management through hostile zones.

Execution · Practiced Mastery
A cinematic open-world western leaning on shooting feel and atmosphere.
Left Alive leans Execution (Practiced Mastery); Red Dead Redemption 2 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.
Left Alive
Clunky shooting and stealth still demand careful manual play
Red Dead Redemption 2
Gunplay and Dead Eye reward aim and timing.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Left Alive
Enemy patrols run fixed detection scripts
Red Dead Redemption 2
Enemies use scripted AI patterns, not adaptation.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Left Alive
Patrol layouts are unknown on first approach
Red Dead Redemption 2
Some hunting and weather randomness, lightly hidden.
Left Alive leans a little harder on optimization, though the gap is small.
Left Alive
Crafting, routing and survivor choices reward planning over reflexes
Red Dead Redemption 2
Loadouts and routes solvable but loose.
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.
