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
Managing an unreliable police roster against random calls and solvable tactics.
Fire Emblem Fates leans Optimization (Pure Optimization); This Is the Police 2 leans Optimization (Systems & Chaos).
Fire Emblem Fates leans a little harder on execution, though the gap is small.
Fire Emblem Fates
Turn-based menu play; no hand-speed demands
This Is the Police 2
Menu management and slow tactical turns need no dexterity
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
This Is the Police 2
Story actors and criminals are scripted
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Fire Emblem Fates
Dual-strike/guard procs and hit rates inject meaningful RNG
This Is the Police 2
Call outcomes and officer quirks roll unpredictably
Fire Emblem Fates leans a little harder on optimization, though the gap is small.
Fire Emblem Fates
Offspring seals, asset/flaw selection, and supports are deeply planned
This Is the Police 2
Roster management, dispatch triage and tactical positioning 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.
