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
Planning augmented routes through dense environments where augment investment and sequencing define efficiency.

Optimization · Pure Optimization
A Viking survival game where preparing properly trivialises each biome boss.
Deus Ex: Mankind Divided leans Optimization (Pure Optimization); Valheim leans Optimization (Pure Optimization).
Deus Ex: Mankind Divided leans a little harder on execution, though the gap is small.
Deus Ex: Mankind Divided
Takedown timing and combat aim have a real ceiling
Valheim
Block-and-parry timing matters in boss fights.
Deus Ex: Mankind Divided leans a little harder on reads, though the gap is small.
Deus Ex: Mankind Divided
Guards are scripted; no opponent models the player
Valheim
Enemies follow scripted AI; no adaptation.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Deus Ex: Mankind Divided
Alert thresholds add some hidden-state wrinkle to infiltration
Valheim
World seed and biome layout introduce mild randomness.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Deus Ex: Mankind Divided
Praxis allocation and approach sequencing optimise mission completion
Valheim
Gear progression and base infrastructure define progress.
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.
