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

Optimization · Pure Optimization
More giant clockwork sandboxes where mapping NPC schedules is the real skill.

Optimization · Pure Optimization
Puzzle-like stealth levels solved by sequencing your band's abilities optimally.
Hitman 2 (2018) leans Optimization (Pure Optimization); Robin Hood: The Legend of Sherwood leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Hitman 2 (2018)
Minimal dexterity needed with a solid plan
Robin Hood: The Legend of Sherwood
Mouse-drawn sword duels add a small dexterity layer
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Hitman 2 (2018)
Clockwork NPC loops, nothing adapts
Robin Hood: The Legend of Sherwood
Guard patrols follow fixed mappable routines
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Hitman 2 (2018)
Mission stories hidden until explored
Robin Hood: The Legend of Sherwood
Unknown layouts only until scouted
Hitman 2 (2018) leans a little harder on optimization, though the gap is small.
Hitman 2 (2018)
Routing, disguises, and unlocks converge on solved runs
Robin Hood: The Legend of Sherwood
Sequencing distractions, knockouts and Merry Men abilities solves each level
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.
