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.

Optimization · Pure Optimization
A wordless robot puzzle adventure where every environmental obstacle has exactly one elegant solution.

Optimization · Pure Optimization
Puzzle-like stealth levels solved by sequencing your band's abilities optimally.
Machinarium leans Optimization (Pure Optimization); Robin Hood: The Legend of Sherwood leans Optimization (Pure Optimization).
Robin Hood: The Legend of Sherwood leans a little harder on execution, though the gap is small.
Machinarium
A handful of mini-games require basic timing and clicking precision
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.
Machinarium
Solo robot puzzle game with no opponent
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.
Machinarium
Arcade mini-games add minor randomness but are skipable
Robin Hood: The Legend of Sherwood
Unknown layouts only until scouted
Machinarium leans a little harder on optimization, though the gap is small.
Machinarium
Environmental logic puzzles are tightly designed closed-world problems
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.
