head to head
The Suffering asks more than Red Dead Redemption 2, and the gap is optimization.

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

Optimization · Practiced Mastery
An action horror game where a death-row inmate fights execution-themed monsters during a prison island breakout.
Red Dead Redemption 2 leans Execution (Practiced Mastery); The Suffering 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.
Red Dead Redemption 2
Gunplay and Dead Eye reward aim and timing.
The Suffering
Fast shooting and the Insanity transformation reward sharp play
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.
The Suffering
Malefactors attack on fixed archetype patterns
The Suffering leans a little harder on variance, though the gap is small.
Red Dead Redemption 2
Some hunting and weather randomness, lightly hidden.
The Suffering
Unknown spawns and morality outcomes on a blind run
The Suffering leans clearly harder on optimization.
Red Dead Redemption 2
Loadouts and routes solvable but loose.
The Suffering
Weapon choice, rage meter use, and routes are 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.
