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

Optimization · Pure Optimization
Solving a civilisation-scale resource and governance puzzle before an ecological deadline.

Optimization · Pure Optimization
A castle-building strategy game where economic optimization and defense planning is the whole test.
Eco leans Optimization (Pure Optimization); Stronghold leans Optimization (Pure Optimization).
Stronghold leans a little harder on execution, though the gap is small.
Eco
No twitch element; all actions are build and craft clicks
Stronghold
minimal, mostly clicking and management
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Eco
Other players add mild human negotiation reads in multiplayer
Stronghold
AI opponents are scripted, minor prediction
Eco leans a little harder on variance, though the gap is small.
Eco
Meteor timer and ecosystem variables carry some hidden uncertainty
Stronghold
minor resource and raid randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Eco
Government systems, specialisation routing, and ecosystem management are richly solvable
Stronghold
economy and castle-building near-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.
