head to head
Worms 2 asks more than Splatoon 3, and the gap is variance.

Execution · Competitive PvP
Turn-based artillery comedy where teams of worms annihilate each other.
Splatoon 3 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 3
Aim, squid movement and ink mobility decide engagements
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 3
Turf and ranked battles hinge on predicting adapting human squads
Worms 2
Human opponents bait positions and hide intentions.
Worms 2 leans clearly harder on variance.
Splatoon 3
Matchmaking and special timing add modest noise
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 3
Gear builds, weapon kits and map control patterns are studied
Worms 2
Weapon economy and positioning theory are studyable.
