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

Optimization · Pure Optimization
Puzzle-like stealth levels solved by sequencing your band's abilities optimally.

Optimization · Pure Optimization
A physics puzzle game about building wobbly towers and bridges from living goo balls.
Robin Hood: The Legend of Sherwood leans Optimization (Pure Optimization); World of Goo 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.
Robin Hood: The Legend of Sherwood
Mouse-drawn sword duels add a small dexterity layer
World of Goo
Placing goo balls needs only mild precision
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Robin Hood: The Legend of Sherwood
Guard patrols follow fixed mappable routines
World of Goo
No opponent exists
Robin Hood: The Legend of Sherwood leans a little harder on variance, though the gap is small.
Robin Hood: The Legend of Sherwood
Unknown layouts only until scouted
World of Goo
Physics are visible and deterministic
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Robin Hood: The Legend of Sherwood
Sequencing distractions, knockouts and Merry Men abilities solves each level
World of Goo
Tower structure and goo economy are solvable per 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.
