head to head
Neither is simply harder - they are hard in different places. SimCity 3000 demands more optimization; The Elder Scrolls V: Skyrim demands more execution.

Optimization · Pure Optimization
A city builder where mastering land value, budgets, and infrastructure math grows the metropolis.

Optimization · Pure Optimization
An open-world RPG mostly about discovering and stacking exploitable progression systems.
SimCity 3000 leans Optimization (Pure Optimization); The Elder Scrolls V: Skyrim leans Optimization (Pure Optimization).
The Elder Scrolls V: Skyrim leans clearly harder on execution.
SimCity 3000
Point-and-click planning; pause anytime.
The Elder Scrolls V: Skyrim
Combat is forgiving; aim and timing rarely punish you.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
SimCity 3000
No adversary exists.
The Elder Scrolls V: Skyrim
Enemy AI is scripted and exploitable; not adaptive.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
SimCity 3000
Random disasters and neighbor deal timing.
The Elder Scrolls V: Skyrim
Loot tables and leveled lists inject mild randomness.
SimCity 3000 leans clearly harder on optimization.
SimCity 3000
Land value, utilities, and ordinance math reward pure system mastery.
The Elder Scrolls V: Skyrim
Skill stacking, enchant loops, and exploits are deeply solvable.
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.
