head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

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

Optimization · Pure Optimization
Sequel RPG where scarce learning points make build planning brutally consequential.
Alekhine's Gun leans Optimization (Pure Optimization); Gothic II 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.
Alekhine's Gun
Timing takedowns matters less than planning them
Gothic II
Directional melee timing against tough fauna
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
Gothic II
No adaptive opposition
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Alekhine's Gun
First visits hide patrol routines and disguise rules
Gothic II
First-run surprises until the island is mapped
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Alekhine's Gun
Mapping routines and disguises reduces missions to solved puzzles
Gothic II
Strict learning-point economy rewards ruthless planning
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.
