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
A management sim where you dispatch police, fire, and medical units while handling emergency calls.

Optimization · Systems & Chaos
A cosy-eldritch fishing game about hauling secrets from dark water.
911 Operator leans Optimization (Pure Optimization); DREDGE leans Optimization (Systems & Chaos).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
911 Operator
Mild time pressure juggling simultaneous calls
DREDGE
Fishing minigames and night dodging, light demands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
911 Operator
Callers are scripted, never model you
DREDGE
Horrors follow fixed rules
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
911 Operator
Incident types and call outcomes arrive randomly
DREDGE
Fish spawns and fog-of-dread unknowns until mapped
911 Operator leans a little harder on optimization, though the gap is small.
911 Operator
Fleet placement, staffing, and dispatch protocol are solvable
DREDGE
Cargo tetris, routes, and upgrades reward planning
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.
