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 mecha RPG where customizing wanzer parts and link systems outweighs battlefield improvisation.

Optimization · Pure Optimization
A survival city builder driven by harsh resource and law optimization.
Front Mission 4 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.
Front Mission 4
Menu-driven turn-based combat
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.
Front Mission 4
Fixed mission AI with set behaviors
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.
Front Mission 4
Accuracy rolls and link-attack triggers
Frostpunk
Scenario events and weather pulses add tension.
Frostpunk leans a little harder on optimization, though the gap is small.
Front Mission 4
Wanzer part builds and pilot skill loadouts are the game
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.
