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

Optimization · Pure Optimization
Survival horror prequel built on swapping two characters with no item boxes.

Optimization · Pure Optimization
Classic open-world RPG where stats and broken crafting systems trump twitch skill.
Resident Evil 0 leans Optimization (Pure Optimization); The Elder Scrolls III: Morrowind leans Optimization (Pure Optimization).
Resident Evil 0 leans a little harder on execution, though the gap is small.
Resident Evil 0
Tank-control combat is modestly demanding
The Elder Scrolls III: Morrowind
Dice-roll combat ignores aim skill
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Resident Evil 0
Enemies follow fixed behaviour
The Elder Scrolls III: Morrowind
No adaptive opposition
Resident Evil 0 leans a little harder on variance, though the gap is small.
Resident Evil 0
Hidden layouts surprise until mapped
The Elder Scrolls III: Morrowind
Hit chances rolled behind the screen
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
