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

Execution · Practiced Mastery
A cinematic open-world western leaning on shooting feel and atmosphere.

Execution · Practiced Mastery
Classic action execution through fixed levels and scripted boss patterns.
Red Dead Redemption 2 leans Execution (Practiced Mastery); Spider-Man leans Execution (Practiced Mastery).
Spider-Man leans a little harder on execution, though the gap is small.
Red Dead Redemption 2
Gunplay and Dead Eye reward aim and timing.
Spider-Man
Swinging, combat and timed escapes need real dexterity
Red Dead Redemption 2 leans a little harder on reads, though the gap is small.
Red Dead Redemption 2
Enemies use scripted AI patterns, not adaptation.
Spider-Man
Villains repeat fixed boss patterns
Red Dead Redemption 2 leans a little harder on variance, though the gap is small.
Red Dead Redemption 2
Some hunting and weather randomness, lightly hidden.
Spider-Man
Level events are scripted and quickly known
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Red Dead Redemption 2
Loadouts and routes solvable but loose.
Spider-Man
Boss patterns and level routes are fully learnable
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.
