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 medieval siege-warfare RTS emphasizing economy management and castle building.

Optimization · Pure Optimization
A harsh old-school MMORPG where full-loot PvP reads and deep hunting-route optimisation define survival.
Stronghold Crusader II 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.
Stronghold Crusader II
unit micro and siege management require dexterity
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.
Stronghold Crusader II
reading human opponents' siege timing and attacks
Tibia
Open-world PvP and ganking involve reading real human opponents
Tibia leans a little harder on variance, though the gap is small.
Stronghold Crusader II
minor resource and combat RNG
Tibia
Rare loot drop rates drive extreme grind variance
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Stronghold Crusader II
economy and siege strategy dominate outcomes
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.
