head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is optimization, and it is a single point.

Optimization · Pure Optimization
A basketball team management simulation game.

Optimization · Pure Optimization
Deep empire optimisation over a hidden map against mappable AI.
Pro Basketball Manager 2017 leans Optimization (Pure Optimization); Sid Meier's Civilization IV 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.

management sim, no physical execution ceiling
Sid Meier's Civilization IV
Turn-based clicks have no physical ceiling
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Pro Basketball Manager 2017
opposing managers create light adaptive pressure
Sid Meier's Civilization IV
Human multiplayer adds diplomacy reads; AI is mappable
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Pro Basketball Manager 2017
match simulation involves random rolls
Sid Meier's Civilization IV
Map generation and unrevealed terrain drive early decisions
Sid Meier's Civilization IV leans a little harder on optimization, though the gap is small.

roster and tactics optimization is the core loop
Sid Meier's Civilization IV
Tech paths, tile yields and expansion math dominate outcomes
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.
