head to head
Syphon Filter 3 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.

Execution · Practiced Mastery
Learning scripted mission layouts and executing aim and stealth under pressure.
Red Dead Redemption 2 leans Execution (Practiced Mastery); Syphon Filter 3 leans Execution (Practiced Mastery).
Syphon Filter 3 leans a little harder on execution, though the gap is small.
Red Dead Redemption 2
Gunplay and Dead Eye reward aim and timing.
Syphon Filter 3
Aim, taser timing and stealth movement carry encounters
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Red Dead Redemption 2
Enemies use scripted AI patterns, not adaptation.
Syphon Filter 3
Enemies run fixed scripts, never model the player
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Red Dead Redemption 2
Some hunting and weather randomness, lightly hidden.
Syphon Filter 3
Enemy placements are scripted-but-unknown on first runs
Syphon Filter 3 leans clearly harder on optimization.
Red Dead Redemption 2
Loadouts and routes solvable but loose.
Syphon Filter 3
Routes, gadget use and mission layouts 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.
