head to head
Neither is simply harder - they are hard in different places. Sid Meier's Colonization demands more variance; The Elder Scrolls V: Skyrim demands more execution.

Optimization · Pure Optimization
A 1994 Sid Meier strategy game about building colonial economies and winning independence.

Optimization · Pure Optimization
An open-world RPG mostly about discovering and stacking exploitable progression systems.
Sid Meier's Colonization leans Optimization (Pure Optimization); The Elder Scrolls V: Skyrim leans Optimization (Pure Optimization).
The Elder Scrolls V: Skyrim leans clearly harder on execution.
Sid Meier's Colonization
Turn-based; hands irrelevant
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.
Sid Meier's Colonization
Royal and rival AI behave on fixed schedules
The Elder Scrolls V: Skyrim
Enemy AI is scripted and exploitable; not adaptive.
Sid Meier's Colonization leans clearly harder on variance.
Sid Meier's Colonization
Random New World maps and native placement vary starts
The Elder Scrolls V: Skyrim
Loot tables and leveled lists inject mild randomness.
Sid Meier's Colonization leans clearly harder on optimization.
Sid Meier's Colonization
Production chains and liberty-bell timing are a solvable economy
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.
