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

Optimization · Practiced Mastery
A meditative zero-gravity survival stroll testing little beyond oxygen route planning.

Optimization · Practiced Mastery
A relaxed co-op collect-a-thon testing little beyond completionist routing.
Adr1ft leans Optimization (Practiced Mastery); LEGO Pirates of the Caribbean: The Video Game leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Adr1ft
Gentle zero-g drifting with mild oxygen pressure
LEGO Pirates of the Caribbean: The Video Game
Forgiving brawling and platforming for all ages
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Adr1ft
No adversary exists in the wreckage
LEGO Pirates of the Caribbean: The Video Game
Enemies are harmless scripted props
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Adr1ft
Debris field layout is fixed once seen
LEGO Pirates of the Caribbean: The Video Game
Collectible locations are fixed, just initially unknown
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Adr1ft
Routing between oxygen canisters is light resource planning
LEGO Pirates of the Caribbean: The Video Game
Completionist collectible routing is the only real puzzle
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.
