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

Optimization · Pure Optimization
A bridge-building physics puzzle testing structural engineering under constraints.

Optimization · Pure Optimization
An open-world RPG mostly about discovering and stacking exploitable progression systems.
Bridge Project leans Optimization (Pure Optimization); The Elder Scrolls V: Skyrim leans Optimization (Pure Optimization).
The Elder Scrolls V: Skyrim leans clearly harder on execution.
Bridge Project
Placing parts is point-and-click, no timing
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.
Bridge Project
No opponent in a physics building puzzle
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.
Bridge Project
Physics deterministic; stress tests are predictable
The Elder Scrolls V: Skyrim
Loot tables and leveled lists inject mild randomness.
Bridge Project leans clearly harder on optimization.
Bridge Project
Designing stable bridges within budget is the entire 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.
