head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Execution · Practiced Mastery
A medieval-flavored Doom prequel built around shield parries and heavy combat.

Execution · Practiced Mastery
Nintendo's branching rail shooter where score medals demand perfected routes.
Doom: The Dark Ages leans Execution (Practiced Mastery); Star Fox 64 leans Execution (Practiced Mastery).
Star Fox 64 leans a little harder on execution, though the gap is small.
Doom: The Dark Ages
Parry timing and shield play demand precise inputs
Star Fox 64
Rail-shooter aim, barrel rolls, and boost timing are everything
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Doom: The Dark Ages
Demon attack patterns are fixed and learnable
Star Fox 64
Entirely scripted bosses and waves
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Doom: The Dark Ages
Encounters fully scripted
Star Fox 64
Fully deterministic once routes are known
Star Fox 64 leans a little harder on optimization, though the gap is small.
Doom: The Dark Ages
Upgrade paths and combat-loop mastery solve fights
Star Fox 64
Medal scores and route branches reward total memorization
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.
