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

Execution · Practiced Mastery
Open-world western about an outlaw forced to hunt down his old gang.

Optimization · Practiced Mastery
A classic Star Wars shooter of maze-like Imperial levels and blaster combat.
Red Dead Redemption leans Execution (Practiced Mastery); Star Wars: Dark Forces 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
Dead Eye softens but gunplay still wants aim
Star Wars: Dark Forces
Blaster aim and movement through trooper waves
Red Dead Redemption leans a little harder on reads, though the gap is small.
Red Dead Redemption
Multiplayer skirmishes add light human prediction
Star Wars: Dark Forces
Stormtrooper AI is fixed and predictable
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Red Dead Redemption
Ambient events and spawns vary mildly
Star Wars: Dark Forces
Maze layouts unknown only on first visit
Star Wars: Dark Forces leans a little harder on optimization, though the gap is small.
Red Dead Redemption
Mission approaches and economy are learnable
Star Wars: Dark Forces
Level navigation and key-hunting are the real test
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.
