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
A cinematic open-world western leaning on shooting feel and atmosphere.

Execution · Practiced Mastery
A movie tie-in testing combo timing against scripted duels.
Red Dead Redemption 2 leans Execution (Practiced Mastery); Star Wars: Episode III - Revenge of the Sith leans Execution (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.
Star Wars: Episode III - Revenge of the Sith
Lightsaber combos and blocks need modest timing
Star Wars: Episode III - Revenge of the Sith leans a little harder on reads, though the gap is small.
Red Dead Redemption 2
Enemies use scripted AI patterns, not adaptation.
Star Wars: Episode III - Revenge of the Sith
Versus duel mode adds light human prediction
Red Dead Redemption 2 leans a little harder on variance, though the gap is small.
Red Dead Redemption 2
Some hunting and weather randomness, lightly hidden.
Star Wars: Episode III - Revenge of the Sith
Encounters are fixed movie-scripted setpieces
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Red Dead Redemption 2
Loadouts and routes solvable but loose.
Star Wars: Episode III - Revenge of the Sith
Combo unlocks and boss patterns are quickly mapped
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.
