head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Practiced Mastery
A dark platformer testing moderate jump and combat execution through fixed levels.

Execution · Practiced Mastery
Gothic action platformer starring a one-eyed undead knight reclaiming his honor.
American McGee's Alice leans Execution (Practiced Mastery); MediEvil 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
MediEvil
stiff swordplay and platforming timing
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
American McGee's Alice
Wonderland enemies follow fixed scripts
MediEvil
skeletons follow fixed patterns
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
American McGee's Alice
Levels are fixed once explored
MediEvil
deterministic levels and secrets
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
MediEvil
chalice hunting and weapon progression routing
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.
