head to head
Worms 2 asks more than Splatoon, and the gap is variance.

Execution · Competitive PvP
Territory control through shooter execution and constant prediction of adapting human teams.

Execution · Competitive PvP
Turn-based artillery comedy where teams of worms annihilate each other.
Splatoon leans Execution (Competitive PvP); Worms 2 leans Execution (Competitive PvP).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Splatoon
Aim, swim-form movement and ink management are constant demands
Worms 2
Ninja rope mastery and pixel-perfect grenade arcs win games.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Splatoon
Human opponents adapt flanks and pushes every match
Worms 2
Human opponents bait positions and hide intentions.
Worms 2 leans clearly harder on variance.
Splatoon
Hidden squids in ink create momentary information gaps
Worms 2
Wind, crate drops and terrain randomness swing turns.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Splatoon
Weapon kits, map control timing and gear builds reward study
Worms 2
Weapon economy and positioning theory are studyable.
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.
