Thief Simulator 2 asks more than The Elder Scrolls V: Skyrim, and the gap is reads.

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

Optimization · Pure Optimization
A stealth sim about casing houses and planning optimal heists.
The Elder Scrolls V: Skyrim leans Optimization (Pure Optimization); Thief Simulator 2 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.
Thief Simulator 2
Lockpicking and stealth timing matter but stay light
Thief Simulator 2 leans clearly harder on reads.
The Elder Scrolls V: Skyrim
Enemy AI is scripted and exploitable; not adaptive.
Thief Simulator 2
NPC patrols follow scripted routes, not adaptive
Thief Simulator 2 leans a little harder on variance, though the gap is small.
The Elder Scrolls V: Skyrim
Loot tables and leveled lists inject mild randomness.
Thief Simulator 2
Loot contents and patrol timing add mild uncertainty
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.
Thief Simulator 2
Planning routes, tools and casing targets is the core
