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
Familiar SM64 routing and movement re-tested with a gun in hand.
DuckTales leans Execution (Practiced Mastery); Super Mario 64 FPS 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
Super Mario 64 FPS
Platform movement plus aiming carries every star
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
Super Mario 64 FPS
Recreated SM64 enemies follow original scripts
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
Super Mario 64 FPS
Levels are known quantities from the source game
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
Super Mario 64 FPS
Star routing and movement tech are well-mapped territory
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.
