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 · Pure Mechanics
Co-op bullet-hell shooter set in a 17th-century British colonial Mars.

Execution · Practiced Mastery
Nintendo's branching rail shooter where score medals demand perfected routes.
Jamestown: Legend of the Lost Colony leans Execution (Pure Mechanics); Star Fox 64 leans Execution (Practiced Mastery).
Jamestown: Legend of the Lost Colony leans a little harder on execution, though the gap is small.
Jamestown: Legend of the Lost Colony
Bullet-dodging precision at high difficulty
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.
Jamestown: Legend of the Lost Colony
Bullet patterns are fully scripted
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.
Jamestown: Legend of the Lost Colony
Deterministic waves every run
Star Fox 64
Fully deterministic once routes are known
Star Fox 64 leans a little harder on optimization, though the gap is small.
Jamestown: Legend of the Lost Colony
Vaunt-chaining score systems and route memorization
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.
