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
A tactical action RPG testing ability sequencing and build choices over reflexes.
Marvel: Ultimate Alliance leans Optimization (Practiced Mastery); Of Orcs and Men 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
Of Orcs and Men
Slowed tactical combat forgives imprecise inputs
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
Of Orcs and Men
Enemy squads follow fixed behaviours
Marvel: Ultimate Alliance leans a little harder on variance, though the gap is small.
Marvel: Ultimate Alliance
some loot and unlock randomness
Of Orcs and Men
Encounters are authored with little randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Marvel: Ultimate Alliance
team bonuses, gear, and skill builds carry difficulty
Of Orcs and Men
Skill queues, rage management and builds decide fights
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.
