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

Optimization · Pure Optimization
A genre-hopping adventure that evolves through gaming history as you play.

Optimization · Pure Optimization
A perk-driven sci-fi RPG won by flaw selection and dialogue routing.
Evoland leans Optimization (Pure Optimization); The Outer Worlds 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.
Evoland
Light Zelda-style action sections
The Outer Worlds
FPS-lite with time-dilation aim
The Outer Worlds leans a little harder on reads, though the gap is small.
Evoland
No adaptive opponent
The Outer Worlds
Scripted enemies
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Evoland
Some random encounters in RPG segments
The Outer Worlds
Loot rolls, dialogue check variance
The Outer Worlds leans a little harder on optimization, though the gap is small.
Evoland
Short, fully mappable progression gimmick
The Outer Worlds
Perks, flaws, dialogue routing rewarded
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.
