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
Optimizing pair-up chains and offspring builds to steamroll deterministically scripted maps.

Optimization · Systems & Chaos
Navigating AP-driven cover-and-overwatch combat while optimizing a mercenary island campaign.
Fire Emblem Fates leans Optimization (Pure Optimization); Jagged Alliance 3 leans Optimization (Systems & Chaos).
Jagged Alliance 3 leans a little harder on execution, though the gap is small.
Fire Emblem Fates
Turn-based menu play; no hand-speed demands
Jagged Alliance 3
Overwatch arc placement and AP budgeting require spatial discipline
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Fire Emblem Fates
AI follows scripted attack priorities, not player modeling
Jagged Alliance 3
Enemy AI is scripted; no faction adapts to your broader strategy
Jagged Alliance 3 leans a little harder on variance, though the gap is small.
Fire Emblem Fates
Dual-strike/guard procs and hit rates inject meaningful RNG
Jagged Alliance 3
Hit percentages, morale checks, and random patrol timing create variance
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Fire Emblem Fates
Offspring seals, asset/flaw selection, and supports are deeply planned
Jagged Alliance 3
Merc hiring, sector control routing, and weapon modding are the optimization 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.
