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
A vault management sim about optimising dwellers, rooms, and resource loops.

Optimization · Pure Optimization
A noir management game where a corrupt retiring police chief juggles dispatches, mobsters, and money.
Fallout Shelter leans Optimization (Pure Optimization); This Is the Police leans Optimization (Pure Optimization).
This Is the Police leans a little harder on execution, though the gap is small.
Fallout Shelter
Tapping menus only
This Is the Police
Menu-driven dispatching, no dexterity
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Fallout Shelter
No opponent
This Is the Police
Mob and city events are scripted
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Fallout Shelter
Incident spawns and lunchbox loot rolls
This Is the Police
Call outcomes and officer rolls are uncertain
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Fallout Shelter
Dweller stats and room layout are fully solvable
This Is the Police
Staffing, dispatch triage, and cash management 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.
