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 match-three game testing efficient board clearing to fund city-building.

Optimization · Pure Optimization
An open-world Caribbean sandbox of ship duels, sword fights, trading, and treasure hunting.
Cradle of Rome leans Optimization (Pure Optimization); Sid Meier's Pirates! leans Optimization (Pure Optimization).
Sid Meier's Pirates! leans a little harder on execution, though the gap is small.
Cradle of Rome
Light click-speed under timers, never decisive
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.
Cradle of Rome
Solo match-three, no opponent to model
Sid Meier's Pirates!
AI captains follow simple fixed behaviours
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Cradle of Rome
Board tile drops are random per move
Sid Meier's Pirates!
Treasure locations, wind, and town states roll randomly
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Cradle of Rome
Planning matches to collect resources builds the city
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.
