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
The 2001 Civilization entry that introduced culture, strategic resources and refined empire micromanagement.

Optimization · Pure Optimization
Juggling rival faction demands and island economics to keep your dictator in power.

No dexterity in a turn-based interface
Tropico 4
Decree-clicking requires no dexterity
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Sid Meier's Civilization III
AI personalities are fixed and mappable

Faction AI follows fixed ideological scripts, not player modeling
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.

Balancing factions, treasury, and production chains is the core loop
