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

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

Optimization · Pure Optimization
Building a medieval trade empire by optimizing routes, cities and economy across Europe.
Anno 1800 leans Optimization (Pure Optimization); Grand Ages: Medieval 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
Grand Ages: Medieval
No twitch input - menus and orders only
Grand Ages: Medieval leans a little harder on reads, though the gap is small.
Anno 1800
AI scripted, not adaptive
Grand Ages: Medieval
AI rivals follow fixed strategy, not adaptive modelling
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
Grand Ages: Medieval
Map and events scripted-but-unknown until explored
Anno 1800 leans a little harder on optimization, though the gap is small.
Anno 1800
supply chains and ratios are the game
Grand Ages: Medieval
Trade routes, city placement and economy are the solvable core
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.
