head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

Execution · Practiced Mastery
A strategy-arcade hybrid mixing map planning with twitchy battle control.

Execution · Competitive PvP
Artillery touch, human prediction and weapon economy in destructible 3D terrain.
North & South leans Execution (Practiced Mastery); Worms 3D 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.
North & South
Arcade battle segments demand real-time unit control
Worms 3D
Judging grenade arcs and wind in 3D takes real touch
Worms 3D leans a little harder on reads, though the gap is small.
North & South
Versus a friend, anticipating map moves and assaults matters
Worms 3D
Predicting where a human hides and strikes next matters
Worms 3D leans a little harder on variance, though the gap is small.
North & South
Random events like storms and raids disrupt plans
Worms 3D
Wind, crate drops and terrain chaos swing turns
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
North & South
Strategic-layer army positioning and economy reward planning
Worms 3D
Weapon economy and positioning math reward planning
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.
