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

Optimization · Pure Optimization
An open-world RPG mostly about discovering and stacking exploitable progression systems.

Optimization · Pure Optimization
A minimal physics puzzle about chaining explosions to reach the goal.
The Elder Scrolls V: Skyrim leans Optimization (Pure Optimization); Zup! X 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.
The Elder Scrolls V: Skyrim
Combat is forgiving; aim and timing rarely punish you.
Zup! X
Minimal dexterity to trigger explosions
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
The Elder Scrolls V: Skyrim
Enemy AI is scripted and exploitable; not adaptive.
Zup! X
Solo - no opponent to model
The Elder Scrolls V: Skyrim leans a little harder on variance, though the gap is small.
The Elder Scrolls V: Skyrim
Loot tables and leveled lists inject mild randomness.
Zup! X
Deterministic physics puzzles, no hidden randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
The Elder Scrolls V: Skyrim
Skill stacking, enchant loops, and exploits are deeply solvable.
Zup! X
Finding the right explosion sequence is the puzzle
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.
