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

Optimization · Pure Optimization
Optimising terror combos against scripted victims to maximise a points score per level.

Optimization · Pure Optimization
A first-person farming game about wrangling adorable slimes for plorts.
Naughty Bear leans Optimization (Pure Optimization); Slime Rancher leans Optimization (Pure Optimization).
Naughty Bear leans a little harder on execution, though the gap is small.
Naughty Bear
Simple melee and chase inputs with low timing demands
Slime Rancher
Vacuum aiming is gentle.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Naughty Bear
Victim bears run scripted panic routines, never modelling you
Slime Rancher
Slimes follow scripted behaviors.
Slime Rancher leans a little harder on variance, though the gap is small.
Naughty Bear
Bear patrols add mild unpredictability per attempt
Slime Rancher
Plort prices and slime spawns vary.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Naughty Bear
Maximising scare-point combos per level is a solvable puzzle
Slime Rancher
Ranch layout and economy 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.
