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
The beloved NES platformer built around Scrooge's pogo cane.

Execution · Practiced Mastery
Dark-fantasy Doom-engine shooter trading shotguns for elven wands and tomes.
DuckTales leans Execution (Practiced Mastery); Heretic 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.
DuckTales
Pogo-cane timing carries the platforming
Heretic
Classic FPS strafing and aim
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
DuckTales
Fixed enemy placements
Heretic
Monsters follow fixed 90s AI
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
DuckTales
Hidden treasures until found
Heretic
Static level layouts
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
DuckTales
Level routes and secrets are memorisable
Heretic
Secret hunting, item hoarding, and route knowledge
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.
