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

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

Optimization · Pure Optimization
A survival city builder driven by harsh resource and law optimization.
Chroma Squad leans Optimization (Pure Optimization); Frostpunk 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.
Chroma Squad
Turn-based commands, no dexterity involved
Frostpunk
Pausable strategy with no input precision.
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
Frostpunk
No adaptive opponent in the survival city.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Chroma Squad
Hit rolls and episode events add modest noise
Frostpunk
Scenario events and weather pulses add tension.
Frostpunk leans a little harder on optimization, though the gap is small.
Chroma Squad
Studio economy, crafting and teamwork combos are the puzzle
Frostpunk
Resource routing, laws, and heat are solvable.
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.
