Execution · Practiced Mastery
A team shooter where aim and positioning against human opponents controls the map.
Madden NFL Football leans Execution (Practiced Mastery); Splatoon 2 leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Madden NFL Football
passing, running, and tackling precision
Splatoon 2
aim and movement decide ink battles
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.

human opponents disguise and read plays
Splatoon 2
predicting human opponent positioning
Madden NFL Football leans a little harder on variance, though the gap is small.
Madden NFL Football
fumble and injury randomness
Splatoon 2
weapon and map rotation randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Madden NFL Football
playbook and roster management depth
Splatoon 2
loadout and turf strategy solvable
