head to head
Metal Gear Solid 2: Sons of Liberty asks more than Red Dead Redemption 2, and the gap is optimization.

Optimization · Practiced Mastery
Threading precise inputs through scripted guard gauntlets aboard a controlled and memorisable facility.

Execution · Practiced Mastery
A cinematic open-world western leaning on shooting feel and atmosphere.
Metal Gear Solid 2: Sons of Liberty leans Optimization (Practiced Mastery); Red Dead Redemption 2 leans Execution (Practiced Mastery).
Metal Gear Solid 2: Sons of Liberty leans a little harder on execution, though the gap is small.
Metal Gear Solid 2: Sons of Liberty
First-person aim and guard reaction windows demand precise input
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.
Metal Gear Solid 2: Sons of Liberty
Guards radio for backup on scripted triggers, not adaptive tactics
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.
Metal Gear Solid 2: Sons of Liberty
Alert timers and item pickups create some hidden-state tension
Red Dead Redemption 2
Some hunting and weather randomness, lightly hidden.
Metal Gear Solid 2: Sons of Liberty leans clearly harder on optimization.
Metal Gear Solid 2: Sons of Liberty
Chokepoint memorisation and radar manipulation are learnable and repeatable
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.
