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
A futuristic city-builder where eco and industrial factions race to settle a flooded Earth.

Optimization · Pure Optimization
A knowledge-based mystery solved by mapping a deterministic solar system.
Anno 2070 leans Optimization (Pure Optimization); Outer Wilds leans Optimization (Pure Optimization).
Outer Wilds leans a little harder on execution, though the gap is small.
Anno 2070
Building and routing, no reflexes
Outer Wilds
Light piloting, mostly forgiving
Anno 2070 leans a little harder on reads, though the gap is small.
Anno 2070
Faction AI is scripted
Outer Wilds
World is fixed; nothing adapts to you
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Anno 2070
Map generation varies resources slightly
Outer Wilds
Loop is deterministic once understood
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Anno 2070
Eco-versus-industry chains reward exact balancing
Outer Wilds
Pure knowledge puzzle - solve the system
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.
