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 knowledge-based mystery solved by mapping a deterministic solar system.

Optimization · Pure Optimization
A city builder where mastering land value, budgets, and infrastructure math grows the metropolis.
Outer Wilds leans Optimization (Pure Optimization); SimCity 3000 leans Optimization (Pure Optimization).
Outer Wilds leans a little harder on execution, though the gap is small.
Outer Wilds
Light piloting, mostly forgiving
SimCity 3000
Point-and-click planning; pause anytime.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Outer Wilds
World is fixed; nothing adapts to you
SimCity 3000
No adversary exists.
SimCity 3000 leans a little harder on variance, though the gap is small.
Outer Wilds
Loop is deterministic once understood
SimCity 3000
Random disasters and neighbor deal timing.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Outer Wilds
Pure knowledge puzzle - solve the system
SimCity 3000
Land value, utilities, and ordinance math reward pure system mastery.
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.
