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 · Pure Optimization
A zombie survival sim where long-term planning outweighs moment-to-moment skill.
Brotato leans Optimization (Systems & Chaos); Project Zomboid leans Optimization (Pure Optimization).
Brotato leans a little harder on execution, though the gap is small.
Brotato
Auto-aim shooting with movement dodging only.
Project Zomboid
Combat is deliberate; precision matters but is slow.
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.
Project Zomboid
Zombies follow scripted behaviour; no adaptation.
Brotato leans a little harder on variance, though the gap is small.
Brotato
Item and weapon rolls dominate runs.
Project Zomboid
Loot spawns and zombie distributions randomized.
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.
Project Zomboid
Skill grinding, base setup, and routing define survival.
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.
