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
Comedy FPS where talking guns crack jokes through an alien bounty-hunting romp.

Execution · Practiced Mastery
Gothic action platformer starring a one-eyed undead knight reclaiming his honor.
High on Life 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.
High on Life
Standard FPS aim and movement gadgets
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.
High on Life
Bounty targets are scripted bosses
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.
High on Life
Fixed encounters and levels
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.
High on Life
Gun ability combos and exploration upgrades
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.
