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

Optimization · Practiced Mastery
Bethesda space RPG with ship and outpost systems.
Deus Ex: Mankind Divided leans Optimization (Pure Optimization); Starfield 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.
Deus Ex: Mankind Divided
Takedown timing and combat aim have a real ceiling
Starfield
Shooter and piloting inputs
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Deus Ex: Mankind Divided
Guards are scripted; no opponent models the player
Starfield
Scripted NPC AI patterns
Starfield leans a little harder on variance, though the gap is small.
Deus Ex: Mankind Divided
Alert thresholds add some hidden-state wrinkle to infiltration
Starfield
Procedural planets, loot variance
Deus Ex: Mankind Divided leans a little harder on optimization, though the gap is small.
Deus Ex: Mankind Divided
Praxis allocation and approach sequencing optimise mission completion
Starfield
Ship building, outpost, perk routing
