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

Optimization · Pure Optimization
A Hitman-style Cold War stealth game about a KGB assassin working sandboxed kill missions.

Optimization · Pure Optimization
An open-world RPG mostly about discovering and stacking exploitable progression systems.
Alekhine's Gun leans Optimization (Pure Optimization); The Elder Scrolls V: Skyrim leans Optimization (Pure Optimization).
Alekhine's Gun leans a little harder on execution, though the gap is small.
Alekhine's Gun
Timing takedowns matters less than planning them
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.
Alekhine's Gun
NPC routines are clockwork, never reactive learning
The Elder Scrolls V: Skyrim
Enemy AI is scripted and exploitable; not adaptive.
Alekhine's Gun leans a little harder on variance, though the gap is small.
Alekhine's Gun
First visits hide patrol routines and disguise rules
The Elder Scrolls V: Skyrim
Loot tables and leveled lists inject mild randomness.
Alekhine's Gun leans a little harder on optimization, though the gap is small.
Alekhine's Gun
Mapping routines and disguises reduces missions to solved puzzles
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.
