head to head
System Shock 2 asks more than The Elder Scrolls V: Skyrim, and the gap is execution.

Optimization · Pure Optimization
An immersive-sim RPG demanding intricate build optimisation and resource management aboard a hostile alien-infested starship.

Optimization · Pure Optimization
An open-world RPG mostly about discovering and stacking exploitable progression systems.
System Shock 2 leans Optimization (Pure Optimization); The Elder Scrolls V: Skyrim leans Optimization (Pure Optimization).
System Shock 2 leans clearly harder on execution.
System Shock 2
Weapon degradation and limited stats moderate the raw aim ceiling
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.
System Shock 2
All enemies are scripted with fixed patrol and attack routines
The Elder Scrolls V: Skyrim
Enemy AI is scripted and exploitable; not adaptive.
System Shock 2 leans clearly harder on variance.
System Shock 2
Random loot locations and psi powers introduce run-to-run variance
The Elder Scrolls V: Skyrim
Loot tables and leveled lists inject mild randomness.
System Shock 2 leans clearly harder on optimization.
System Shock 2
Deep build tree and resource conservation define the entire skill ceiling
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.
