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
Tactical grid combat plus studio management, both solvable with planning.

Optimization · Pure Optimization
JRPG where you program party AI through its gambit system.
Chroma Squad leans Optimization (Pure Optimization); Final Fantasy XII leans Optimization (Pure Optimization).
Final Fantasy XII leans a little harder on execution, though the gap is small.
Chroma Squad
Turn-based commands, no dexterity involved
Final Fantasy XII
Gambits automate combat away from the hands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Chroma Squad
Enemy AI follows simple mappable rules
Final Fantasy XII
Enemy AI is fixed and exploitable
Chroma Squad leans a little harder on variance, though the gap is small.
Chroma Squad
Hit rolls and episode events add modest noise
Final Fantasy XII
Rare spawns and drop RNG
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Chroma Squad
Studio economy, crafting and teamwork combos are the puzzle
Final Fantasy XII
Programming gambit logic IS the gameplay
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.
