head to head
Worms 2 asks more than Mini Royale, and the gap is optimization.

Execution · Competitive PvP
Battle-royale gunfights testing aim and positioning reads under loot randomness.

Execution · Competitive PvP
Turn-based artillery comedy where teams of worms annihilate each other.
Mini Royale 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.
Mini Royale
Aimbot would dominate every toy-soldier firefight
Worms 2
Ninja rope mastery and pixel-perfect grenade arcs win games.
Worms 2 leans a little harder on reads, though the gap is small.
Mini Royale
Fifty human players to predict in positioning and pushes
Worms 2
Human opponents bait positions and hide intentions.
Mini Royale leans a little harder on variance, though the gap is small.
Mini Royale
Loot spawns and circle placement shake up every match
Worms 2
Wind, crate drops and terrain randomness swing turns.
Worms 2 leans clearly harder on optimization.
Mini Royale
Drop spots and loadout knowledge form a thin solvable layer
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.
