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
Hex-based tactical battles testing unit preservation and turn-limit route planning.

Optimization · Pure Optimization
A calendar-driven JRPG carried by persona fusion and social-link planning.
Fantasy Wars leans Optimization (Pure Optimization); Persona 4 Golden leans Optimization (Pure Optimization).
Persona 4 Golden leans a little harder on execution, though the gap is small.
Fantasy Wars
Turn-based hex orders need no dexterity
Persona 4 Golden
Turn-based, no input demand
Fantasy Wars leans a little harder on reads, though the gap is small.
Fantasy Wars
Multiplayer hotseat adds light human prediction
Persona 4 Golden
Scripted enemies
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Fantasy Wars
Hit-chance rolls and fog create swing moments
Persona 4 Golden
Weakness and crit rolls
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Fantasy Wars
Unit upgrades, terrain and turn-limit routing reward deep calculation
Persona 4 Golden
Persona fusion and calendar routing rewarded
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.
