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

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

Optimization · Systems & Chaos
Gothic turn-based roguelike where managing stress and bad dice is the real fight.
Borderlands 2 leans Optimization (Systems & Chaos); Darkest Dungeon leans Optimization (Systems & Chaos).
Borderlands 2 leans clearly harder on execution.
Borderlands 2
Aim matters but generous hit feel
Darkest Dungeon
turn-based, no dexterity
Borderlands 2 leans a little harder on reads, though the gap is small.
Borderlands 2
Enemies are scripted loot fodder
Darkest Dungeon
no adaptive opponent
Darkest Dungeon leans a little harder on variance, though the gap is small.
Borderlands 2
Procedurally generated weapon drops vary
Darkest Dungeon
crits, stress events, and dungeon rolls punish plans
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Borderlands 2
Skill trees and gear math heavily solved
Darkest Dungeon
party comps and risk management are deeply 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.
