head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, 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 Caribbean sandbox of ship duels, sword fights, trading, and treasure hunting.
Alekhine's Gun leans Optimization (Pure Optimization); Sid Meier's Pirates! 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
Sid Meier's Pirates!
Sword duel timing and ship-handling minigames
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
Sid Meier's Pirates!
AI captains follow simple fixed behaviours
Sid Meier's Pirates! leans a little harder on variance, though the gap is small.
Alekhine's Gun
First visits hide patrol routines and disguise rules
Sid Meier's Pirates!
Treasure locations, wind, and town states roll randomly
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
Sid Meier's Pirates!
Trade routes, faction standing, and career planning dominate
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.
