head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is optimization, and it is a single point.

Optimization · Pure Optimization
Designing and optimizing a theme park's layout, pricing, and guest flow to maximize satisfaction and profit.

Optimization · Pure Optimization
An open-world RPG mostly about discovering and stacking exploitable progression systems.
Planet Coaster leans Optimization (Pure Optimization); The Elder Scrolls V: Skyrim leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Planet Coaster
Precise track and scenery placement rewards manual dexterity
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.
Planet Coaster
No adaptive opponent; guests follow scripted happiness rules
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.
Planet Coaster
Guest mood noise is low and quickly mappable
The Elder Scrolls V: Skyrim
Loot tables and leveled lists inject mild randomness.
Planet Coaster leans a little harder on optimization, though the gap is small.
Planet Coaster
Queue routing, pricing, and ride placement are the solvable core
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.
