head to head
Borderlands 2 asks more than RimWorld, and the gap is execution.

Optimization · Systems & Chaos
Loot-shooter RPG built on gear chasing.

Optimization · Systems & Chaos
A colony sim where the storyteller's randomness tests your designed defenses.
Borderlands 2 leans Optimization (Systems & Chaos); RimWorld leans Optimization (Systems & Chaos).
Borderlands 2 leans clearly harder on execution.
Borderlands 2
Aim matters but generous hit feel
RimWorld
Pausable, no input precision required.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Borderlands 2
Enemies are scripted loot fodder
RimWorld
Storyteller AI is randomised, not adaptive to you.
RimWorld leans a little harder on variance, though the gap is small.
Borderlands 2
Procedurally generated weapon drops vary
RimWorld
Raids, weather, and pawn traits are heavily random.
RimWorld leans a little harder on optimization, though the gap is small.
Borderlands 2
Skill trees and gear math heavily solved
RimWorld
Colony layout, work priorities, and defenses solvable.
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.
