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
Supernatural western turn-based tactics where a luck meter replaces pure hit-chance dice.

Optimization · Pure Optimization
Deep empire optimisation over a hidden map against mappable AI.
Hard West 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.
Hard West
Turn-based; no physical demands
Sid Meier's Civilization IV
Turn-based clicks have no physical ceiling
Sid Meier's Civilization IV leans a little harder on reads, though the gap is small.
Hard West
AI follows fixed tactical scripts
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.
Hard West
Luck meter tames RNG but cards and shots vary
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.
Hard West
Positioning, ability combos, and luck-system math dominate
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.
