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 dark platformer testing moderate jump and combat execution through fixed levels.

Execution · Practiced Mastery
A cinematic open-world western leaning on shooting feel and atmosphere.
American McGee's Alice leans Execution (Practiced Mastery); Red Dead Redemption 2 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.
American McGee's Alice
Floaty platforming and weapon timing need moderate precision
Red Dead Redemption 2
Gunplay and Dead Eye reward aim and timing.
Red Dead Redemption 2 leans a little harder on reads, though the gap is small.
American McGee's Alice
Wonderland enemies follow fixed scripts
Red Dead Redemption 2
Enemies use scripted AI patterns, not adaptation.
Red Dead Redemption 2 leans a little harder on variance, though the gap is small.
American McGee's Alice
Levels are fixed once explored
Red Dead Redemption 2
Some hunting and weather randomness, lightly hidden.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
American McGee's Alice
Weapon selection per enemy and learned jump routes
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.
