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
Beautiful 19th-century city-builder ruled by production ratios.

Optimization · Pure Optimization
A grand strategy game of conquering ancient China by managing hundreds of officers and painting the map your color.
Anno 1800 leans Optimization (Pure Optimization); Romance of the Three Kingdoms XIV 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.
Anno 1800
pausable, no twitch
Romance of the Three Kingdoms XIV
Turn-based menus, zero dexterity
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Anno 1800
AI scripted, not adaptive
Romance of the Three Kingdoms XIV
AI warlords follow learnable behavior patterns
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Anno 1800
minor trade fluctuations
Romance of the Three Kingdoms XIV
Officer events and AI moves add light fog
Anno 1800 leans a little harder on optimization, though the gap is small.
Anno 1800
supply chains and ratios are the game
Romance of the Three Kingdoms XIV
Territory painting, officer assignment, and logistics are deeply solvable
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.
