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
A grand strategy wargame about economy, diplomacy, and conquest across history.

Optimization · Pure Optimization
Fantasy 4X with strong asymmetric factions and quest paths.
Age of History III leans Optimization (Pure Optimization); Endless Legend 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.
Age of History III
Map clicks need no timing or twitch
Endless Legend
turn-based
Age of History III leans a little harder on reads, though the gap is small.
Age of History III
AI nations follow doctrine; humans can adapt
Endless Legend
scripted AI, limited MP
Endless Legend leans a little harder on variance, though the gap is small.
Age of History III
Battle outcomes and events add some chance
Endless Legend
quest and tech rolls
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Age of History III
Economy, diplomacy and conquest planning are the whole game
Endless Legend
faction-specific yield optimization
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.
