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
Optimizing affinity paths and tech web choices on a randomized alien frontier.

Optimization · Pure Optimization
Solving a civilisation-scale resource and governance puzzle before an ecological deadline.
Civilization: Beyond Earth leans Optimization (Pure Optimization); Eco leans Optimization (Pure Optimization).
Civilization: Beyond Earth leans a little harder on execution, though the gap is small.
Civilization: Beyond Earth
Point-and-click turn actions; nothing physical
Eco
No twitch element; all actions are build and craft clicks
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Civilization: Beyond Earth
Faction AI uses static scripts, not player-reactive strategies
Eco
Other players add mild human negotiation reads in multiplayer
Civilization: Beyond Earth leans a little harder on variance, though the gap is small.
Civilization: Beyond Earth
Alien spawns and fog of war add manageable hidden elements
Eco
Meteor timer and ecosystem variables carry some hidden uncertainty
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Civilization: Beyond Earth
Affinity choices and tech web routing define victory conditions deeply
Eco
Government systems, specialisation routing, and ecosystem management are richly 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.
