head to head
Splatoon 2 asks more than It Takes Two, and the gap is reads.

Execution · Practiced Mastery
A co-op puzzle-platformer that tests physical coordination and communication across a wide variety of co-designed mechanics.

Execution · Practiced Mastery
A team shooter where aim and positioning against human opponents controls the map.
It Takes Two leans Execution (Practiced Mastery); Splatoon 2 leans Execution (Practiced Mastery).
Splatoon 2 leans a little harder on execution, though the gap is small.
It Takes Two
Co-op platforming demands tight timing, coordination, and spatial precision
Splatoon 2
aim and movement decide ink battles
Splatoon 2 leans clearly harder on reads.
It Takes Two
Human partner requires some coordination reads but not competitive prediction
Splatoon 2
predicting human opponent positioning
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
It Takes Two
Puzzle solutions are fixed; little hidden randomness
Splatoon 2
weapon and map rotation randomness
Splatoon 2 leans a little harder on optimization, though the gap is small.
It Takes Two
Each chapter has an optimal movement approach once mechanics are learned
Splatoon 2
loadout and turf strategy 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.
