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
Building a medieval trade empire by optimizing routes, cities and economy across Europe.

Optimization · Pure Optimization
An economy and layout optimization puzzle about keeping a small simulated city solvent.
Grand Ages: Medieval leans Optimization (Pure Optimization); SimCity 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.
Grand Ages: Medieval
No twitch input - menus and orders only
SimCity
Pause-friendly building removes any physical test
Grand Ages: Medieval leans a little harder on reads, though the gap is small.
Grand Ages: Medieval
AI rivals follow fixed strategy, not adaptive modelling
SimCity
Region multiplayer is cooperative, not adversarial prediction
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Ages: Medieval
Map and events scripted-but-unknown until explored
SimCity
Disasters and agent simulation quirks add mild randomness
Grand Ages: Medieval leans a little harder on optimization, though the gap is small.
Grand Ages: Medieval
Trade routes, city placement and economy are the solvable core
SimCity
Zoning, traffic flow and specialisation economies are the whole game
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.
