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 colonial-fantasy RPG won by faction routing and build optimization.

Optimization · Pure Optimization
A landmark strategy game combining a turn-based campaign for control of Rome with massive real-time battles.
Greedfall leans Optimization (Pure Optimization); Rome: Total War 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.
Greedfall
Lock-on action combat, modest demand
Rome: Total War
Real-time battle micro rewards quick unit handling
Rome: Total War leans a little harder on reads, though the gap is small.
Greedfall
Scripted enemy patterns
Rome: Total War
Optional multiplayer battles; campaign AI is mappable
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Greedfall
Loot and check rolls
Rome: Total War
Diplomacy and AI moves add modest fog
Rome: Total War leans a little harder on optimization, though the gap is small.
Greedfall
Faction routing, builds, crafting central
Rome: Total War
Campaign economy, recruitment, and battle tactics are 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.
