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 · Systems & Chaos
Wave-survival shooter where a potato juggles weapons against alien hordes.

Optimization · Systems & Chaos
An ARPG loot grind about chasing affix rolls to feed a damage-stack build.
Brotato leans Optimization (Systems & Chaos); Diablo IV leans Optimization (Systems & Chaos).
Brotato leans a little harder on execution, though the gap is small.
Brotato
Auto-aim shooting with movement dodging only.
Diablo IV
Clicking and dodging are light; gear carries you.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Brotato
Scripted enemy waves.
Diablo IV
Enemies and bosses are scripted; no adaptive opponent.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Brotato
Item and weapon rolls dominate runs.
Diablo IV
Loot rolls, affixes, and uniques drive every session.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Brotato
Build crafting between waves is the core loop.
Diablo IV
Paragon, aspects, and damage buckets are solvable theorycraft.
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.
