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

Optimization · Pure Optimization
An open-world action RPG blending clunky combat timing with long-haul character and faction planning.

Optimization · Pure Optimization
A scripted RPG where pattern-learning and pacifist routing carry you.
Gothic 3 leans Optimization (Pure Optimization); Undertale 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 3
Real-time melee timing and kiting matter.
Undertale
Bullet-hell dodging in scripted patterns
Undertale leans a little harder on reads, though the gap is small.
Gothic 3
Wildlife and orcs follow fixed AI.
Undertale
NPCs follow fixed dialogue trees, not adaptive
Gothic 3 leans a little harder on variance, though the gap is small.
Gothic 3
Unknown world content on first run.
Undertale
Minimal randomness in encounters
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Gothic 3
Learning points, faction routes, and gear progression decide power.
Undertale
Learning fixed boss patterns and mercy routes wins
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.
