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

Optimization · Systems & Chaos
Excavating a procedurally generated underground world and solving its layered boss and crafting progression.

Optimization · Pure Optimization
A colorful loot ARPG where theorycrafting builds beats anything your hands do.
Core Keeper leans Optimization (Systems & Chaos); Torchlight II leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Core Keeper
Boss fights and melee require learned dodge timing
Torchlight II
Faster combat asks for dodging and skill timing
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Core Keeper
All bosses and enemies are scripted with fixed patterns
Torchlight II
Enemies are scripted swarms, never adaptive
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Core Keeper
World seed, ore placement, and loot drops are randomised
Torchlight II
Loot rolls and random maps drive the chase
Torchlight II leans a little harder on optimization, though the gap is small.
Core Keeper
Mining routes, crafting progression, and boss order are systematic
Torchlight II
Skill trees and gear synergies decide character power
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.
