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 · Practiced Mastery
A co-op teen survival horror where light is a weapon and dead classmates stay dead.

Optimization · Systems & Chaos
Puzzle adventure about coaxing a giant half-tame creature through ancient ruins.
ObsCure leans Optimization (Practiced Mastery); The Last Guardian leans Optimization (Systems & Chaos).
ObsCure leans a little harder on execution, though the gap is small.
ObsCure
Light aiming and flashlight management
The Last Guardian
Slow climbing and platforming, very forgiving
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
ObsCure
Scripted monster encounters
The Last Guardian
Trico is willful but not modeling you adversarially
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
ObsCure
Permadeath partners and darkness hide information
The Last Guardian
Trico's unpredictable compliance adds noise
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
ObsCure
Resource routing and light tactics are learnable
The Last Guardian
Environmental puzzles with intended solutions
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.
