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 4X-strategy hybrid about controlling Arrakis through economy and intrigue.

Optimization · Pure Optimization
Gunpowder-era Total War blending empire management with line battles.
Dune: Spice Wars leans Optimization (Pure Optimization); Empire: 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.
Dune: Spice Wars
Low-APM real-time control
Empire: Total War
Real-time battle micro is modest
Dune: Spice Wars leans a little harder on reads, though the gap is small.
Dune: Spice Wars
Human multiplayer politics adapt; AI doesn't
Empire: Total War
Multiplayer line-battle feints exist
Dune: Spice Wars leans a little harder on variance, though the gap is small.
Dune: Spice Wars
Map layout, sandworms, and hidden intel
Empire: Total War
Campaign AI and battle dice noise
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Dune: Spice Wars
Spice economy, councils, and tech are deeply optimizable
Empire: Total War
Campaign economy and line-infantry tactics are mappable
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.
