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

Optimization · Pure Optimization
Pure factory-layout optimization with no pressure, randomness or opponent.

Optimization · Pure Optimization
An open-world RPG mostly about discovering and stacking exploitable progression systems.
Shapez leans Optimization (Pure Optimization); The Elder Scrolls V: Skyrim leans Optimization (Pure Optimization).
The Elder Scrolls V: Skyrim leans clearly harder on execution.
Shapez
Placing belts has no time pressure at all
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.
Shapez
No adversary exists anywhere
The Elder Scrolls V: Skyrim
Enemy AI is scripted and exploitable; not adaptive.
The Elder Scrolls V: Skyrim leans a little harder on variance, though the gap is small.
Shapez
The infinite map's shapes are mappable immediately
The Elder Scrolls V: Skyrim
Loot tables and leveled lists inject mild randomness.
Shapez leans clearly harder on optimization.
Shapez
Designing efficient cutting and merging factories IS the game
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.
