head to head
Not a Hero asks more than Red Dead Redemption 2, and the gap is execution.

Execution · Practiced Mastery
Twitchy cover-shooter rooms that reward drilled execution and memorised routes.

Execution · Practiced Mastery
A cinematic open-world western leaning on shooting feel and atmosphere.
Not a Hero leans Execution (Practiced Mastery); Red Dead Redemption 2 leans Execution (Practiced Mastery).
Not a Hero leans clearly harder on execution.
Not a Hero
Slide-cancels, snap cover and reload timing decide every room
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.
Not a Hero
Enemies follow fixed behaviours, nothing adapts to you
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.
Not a Hero
Minor enemy spawn jitter, levels otherwise deterministic
Red Dead Redemption 2
Some hunting and weather randomness, lightly hidden.
Not a Hero leans clearly harder on optimization.
Not a Hero
Learning room layouts and routing kills enables full-clear runs
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.
