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 · Mind & Math
An economy-scaling war of build orders, scouting and multi-planet attention.

Optimization · Mind & Math
Age-spanning RTS where city caps, territory borders, and tech-age races combine economics with military pressure.
Planetary Annihilation leans Optimization (Mind & Math); Rise of Nations leans Optimization (Mind & Math).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Planetary Annihilation
Multi-planet macro demands relentless APM and attention splitting
Rise of Nations
Rare great-wonder timing and military grouping need some precision
Rise of Nations leans a little harder on reads, though the gap is small.
Planetary Annihilation
Scouting and out-guessing a human's expansion plan matters constantly
Rise of Nations
Opponent nation pick and age-rush timing must be predicted
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Planetary Annihilation
Procedural systems and fog hide early information
Rise of Nations
Map resource placement and wonder race timing add moderate uncertainty
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Planetary Annihilation
Economy scaling and build orders dominate - near-solvable openings
Rise of Nations
Territory cap optimization and age-advancement sequencing are deeply 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.
