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

Sid Meier's Civilization IV: Colonization
Turn-based clicks - no physical layer
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Fire Emblem: Three Houses
AI follows fixed aggression rules
Sid Meier's Civilization IV: Colonization
AI rivals follow mappable tendencies
Sid Meier's Civilization IV: Colonization leans a little harder on variance, though the gap is small.
Fire Emblem: Three Houses
Hit rates and crit RNG affect runs
Sid Meier's Civilization IV: Colonization
Map generation and exploration hide early information
