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
Blizzard's mobile Diablo where loot RNG and paid gem systems drive character power.
Brotato leans Optimization (Systems & Chaos); Diablo Immortal 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 Immortal
Touch-friendly combat with dodge timing
Diablo Immortal leans a little harder on reads, though the gap is small.
Brotato
Scripted enemy waves.
Diablo Immortal
PvP battlegrounds exist but gear usually decides
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 Immortal
Legendary gem and loot RNG, heavily monetized
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 Immortal
Resonance, paragon, set optimization dominate 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.
