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

Optimization · Pure Optimization
A harsh old-school MMORPG where full-loot PvP reads and deep hunting-route optimisation define survival.
ARK: Survival Evolved leans Optimization (Pure Optimization); Tibia 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.
ARK: Survival Evolved
Shooting and kiting matter in raids
Tibia
Full-loot hunting and PvP require manual targeting and spell usage
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
ARK: Survival Evolved
Tribe warfare involves human deception and politics
Tibia
Open-world PvP and ganking involve reading real human opponents
ARK: Survival Evolved leans a little harder on variance, though the gap is small.
ARK: Survival Evolved
Taming rolls, spawns, and surprise raids
Tibia
Rare loot drop rates drive extreme grind variance
Tibia leans a little harder on optimization, though the gap is small.
ARK: Survival Evolved
Breeding lines, base design, and farming dominate
Tibia
Vocation builds, spawn routing, and task management are extensively solved
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.
