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

Optimization · Pure Optimization
Sequel RPG where scarce learning points make build planning brutally consequential.

Optimization · Pure Optimization
Crafting-tree planning and needs management under light zombie pressure.
Gothic II leans Optimization (Pure Optimization); How to Survive leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Gothic II
Directional melee timing against tough fauna
How to Survive
Twin-stick zombie kiting needs modest aim
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Gothic II
No adaptive opposition
How to Survive
Zombies are mindless scripted pressure
How to Survive leans a little harder on variance, though the gap is small.
Gothic II
First-run surprises until the island is mapped
How to Survive
Scavenged materials and island layouts are unknown until explored
Gothic II leans a little harder on optimization, though the gap is small.
Gothic II
Strict learning-point economy rewards ruthless planning
How to Survive
Crafting trees and needs management decide 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.
