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 · Practiced Mastery
Co-op superhero brawler about assembling the right four-hero squad and builds.

Optimization · Pure Optimization
An open-world RPG mostly about discovering and stacking exploitable progression systems.
Marvel: Ultimate Alliance leans Optimization (Practiced Mastery); The Elder Scrolls V: Skyrim leans Optimization (Pure Optimization).
Marvel: Ultimate Alliance leans a little harder on execution, though the gap is small.
Marvel: Ultimate Alliance
brawling and dodge timing are forgiving
The Elder Scrolls V: Skyrim
Combat is forgiving; aim and timing rarely punish you.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Marvel: Ultimate Alliance
enemies are scripted mobs
The Elder Scrolls V: Skyrim
Enemy AI is scripted and exploitable; not adaptive.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Marvel: Ultimate Alliance
some loot and unlock randomness
The Elder Scrolls V: Skyrim
Loot tables and leveled lists inject mild randomness.
The Elder Scrolls V: Skyrim leans a little harder on optimization, though the gap is small.
Marvel: Ultimate Alliance
team bonuses, gear, and skill builds carry difficulty
The Elder Scrolls V: Skyrim
Skill stacking, enchant loops, and exploits are deeply solvable.
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.
