Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Halo 2: Anniversary
Predicting human positioning and power-weapon pushes is constant
Splatoon
Human opponents adapt flanks and pushes every match
Variance2 vs 2
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Halo 2: Anniversary
Static spawns and timers leave little true randomness
Splatoon
Hidden squids in ink create momentary information gaps
Optimization5 vs 5
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Halo 2: Anniversary
Weapon timers, map control and campaign routes are learnable systems
Splatoon
Weapon kits, map control timing and gear builds reward study
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.
