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.

Variance · Light / Casual
A relaxing hidden-object game finding 100 cats in alien scenes.

Variance · Systems & Chaos
A short first-person horror game testing nerve against scripted home invasion scares.
100 Aliens Cats leans Variance (Light / Casual); Evil leans Variance (Systems & Chaos).
Evil leans a little harder on execution, though the gap is small.
100 Aliens Cats
Pointing and clicking needs no dexterity
Evil
Walking and looking; minimal physical demand
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
100 Aliens Cats
Solo hidden-object game with no opponent
Evil
Scare events are scripted, not an adaptive mind
Evil leans a little harder on variance, though the gap is small.
100 Aliens Cats
Cat positions are hidden until found
Evil
Hidden scares and events drive the unknown tension
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
100 Aliens Cats
Methodical searching speeds completion
Evil
Figuring out what to do next is the small loop
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.
