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 · Practiced Mastery
Nemesis-system sequel that adds orc army management and fortress sieges.

Optimization · Pure Optimization
An open-world Caribbean sandbox of ship duels, sword fights, trading, and treasure hunting.
Middle-earth: Shadow of War leans Optimization (Practiced Mastery); Sid Meier's Pirates! leans Optimization (Pure Optimization).
Middle-earth: Shadow of War leans a little harder on execution, though the gap is small.
Middle-earth: Shadow of War
Same counter-heavy combat as its predecessor
Sid Meier's Pirates!
Sword duel timing and ship-handling minigames
Middle-earth: Shadow of War leans a little harder on reads, though the gap is small.
Middle-earth: Shadow of War
Nemesis system mimics adaptation but follows knowable rules
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.
Middle-earth: Shadow of War
Random orc traits, betrayals, and fortress compositions
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.
Middle-earth: Shadow of War
Army building and siege planning layer on top
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.
