head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Pure Mechanics
A first-person cyberpunk slasher where everything dies in one hit, including you.

Execution · Pure Mechanics
Co-op bullet-hell shooter set in a 17th-century British colonial Mars.
Ghostrunner leans Execution (Pure Mechanics); Jamestown: Legend of the Lost Colony leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Ghostrunner
One-hit-death parkour and slashing demand near-perfect inputs
Jamestown: Legend of the Lost Colony
Bullet-dodging precision at high difficulty
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Ghostrunner
Enemy placements are fixed
Jamestown: Legend of the Lost Colony
Bullet patterns are fully scripted
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Ghostrunner
Deterministic levels
Jamestown: Legend of the Lost Colony
Deterministic waves every run
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Ghostrunner
Route planning and enemy-order solutions define fast clears
Jamestown: Legend of the Lost Colony
Vaunt-chaining score systems and route 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.
