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 dinosaur survival game about taming, building, and tribal warfare on a hostile island.

Optimization · Practiced Mastery
A space-strategy adventure mixing ship combat with empire resource management.
ARK: Survival Evolved leans Optimization (Pure Optimization); Star Control 3 leans Optimization (Practiced Mastery).
Star Control 3 leans a little harder on execution, though the gap is small.
ARK: Survival Evolved
Shooting and kiting matter in raids
Star Control 3
Ship melee combat needs decent aim and maneuvering
ARK: Survival Evolved leans a little harder on reads, though the gap is small.
ARK: Survival Evolved
Tribe warfare involves human deception and politics
Star Control 3
AI captains use fixed tactics; some PvP melee allows prediction
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
ARK: Survival Evolved
Taming rolls, spawns, and surprise raids
Star Control 3
Exploration and resource discovery are scripted-but-unknown
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
ARK: Survival Evolved
Breeding lines, base design, and farming dominate
Star Control 3
Fleet building, colonization and resource management drive progress
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.
