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
Managing galactic economy and fleet counters, with prediction mattering against humans.

Optimization · Mind & Math
Counter-picking units and out-planning opponents with your voice instead of clicks.
Star Wars: Empire at War leans Optimization (Pure Optimization); Tom Clancy's EndWar leans Optimization (Mind & Math).
Star Wars: Empire at War leans a little harder on execution, though the gap is small.
Star Wars: Empire at War
Some battle micro, but APM never dominates outcomes
Tom Clancy's EndWar
Voice commands remove most mechanical demand by design
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Star Wars: Empire at War
Multiplayer galactic feints and fleet composition mind-games matter
Tom Clancy's EndWar
Multiplayer theatre battles reward predicting enemy unit commitments
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Star Wars: Empire at War
Fog of war hides enemy fleets until scouted
Tom Clancy's EndWar
Fog of war hides compositions until scouted
Star Wars: Empire at War leans a little harder on optimization, though the gap is small.
Star Wars: Empire at War
Economy, tech order and counter-unit composition decide campaigns
Tom Clancy's EndWar
Rock-paper-scissors unit counters and upgrade economy are the solvable core
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.
