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

Optimization · Pure Optimization
An open-world Caribbean sandbox of ship duels, sword fights, trading, and treasure hunting.

Optimization · Practiced Mastery
Optimising a base-building and crafting loop against scripted mutant threats in a dense forest.
Sid Meier's Pirates! leans Optimization (Pure Optimization); Sons of the Forest leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Sid Meier's Pirates!
Sword duel timing and ship-handling minigames
Sons of the Forest
Ranged and melee combat demands aim and timing
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Sid Meier's Pirates!
AI captains follow simple fixed behaviours
Sons of the Forest
Mutant AI follows scripted patterns regardless of player strategy
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Sid Meier's Pirates!
Treasure locations, wind, and town states roll randomly
Sons of the Forest
Enemy spawns and loot locations inject session-level randomness
Sid Meier's Pirates! leans a little harder on optimization, though the gap is small.
Sid Meier's Pirates!
Trade routes, faction standing, and career planning dominate
Sons of the Forest
Base construction and resource routing reward systematic 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.
