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.

Execution · Practiced Mastery
An endless runner testing reaction timing across Spider-Man multiverse stages.

Execution · Practiced Mastery
A campy 16-bit run-and-gun about rescuing neighbors from B-movie monsters.
Marvel Spider-Man Unlimited leans Execution (Practiced Mastery); Zombies Ate My Neighbors leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Marvel Spider-Man Unlimited
Reaction timing on swiping and dodging carries runs
Zombies Ate My Neighbors
Dodging monsters while sniping with squirt guns
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Marvel Spider-Man Unlimited
Endless runner, no opponent to model
Zombies Ate My Neighbors
Monster movie AI is fully patterned
Marvel Spider-Man Unlimited leans a little harder on variance, though the gap is small.
Marvel Spider-Man Unlimited
Randomized obstacle spawns add some chaos
Zombies Ate My Neighbors
Victim placement varies slightly per level
Zombies Ate My Neighbors leans a little harder on optimization, though the gap is small.
Marvel Spider-Man Unlimited
Character collection and upgrades improve scores
Zombies Ate My Neighbors
Weapon-versus-monster matchups and level routing
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.
