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 · Practiced Mastery
Sci-fi horror RPG blending Squaresoft turn systems with real-time dodging in 1997 Manhattan.

Optimization · Pure Optimization
An open world where build optimisation dissolves every combat challenge.
Parasite Eve leans Optimization (Practiced Mastery); The Elder Scrolls V: Skyrim - Special Edition 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.
Parasite Eve
Active-time dodging between attack windows
The Elder Scrolls V: Skyrim - Special Edition
Combat timing matters little; difficulty bends to your build
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Parasite Eve
Mitochondrial monsters follow fixed scripts
The Elder Scrolls V: Skyrim - Special Edition
Draugr and dragons run scripted AI packages
Parasite Eve leans a little harder on variance, though the gap is small.
Parasite Eve
Random drops and first-run boss surprises
The Elder Scrolls V: Skyrim - Special Edition
Loot rolls and radiant quests add minor mapped randomness
The Elder Scrolls V: Skyrim - Special Edition leans a little harder on optimization, though the gap is small.
Parasite Eve
Weapon tuning and Parasite Energy management
The Elder Scrolls V: Skyrim - Special Edition
Perk, crafting and stealth-archer loops trivially solve combat
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.
