head to head
Kid Icarus: Uprising asks more than Marvel's Spider-Man 2, and the gap is reads.

Execution · Practiced Mastery
A frenetic 3DS action shooter mixing rail flight, ground combat, and weapon fusion.

Execution · Practiced Mastery
Two Spider-Men, faster traversal, and deeper combo systems.
Kid Icarus: Uprising leans Execution (Practiced Mastery); Marvel's Spider-Man 2 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.
Kid Icarus: Uprising
Stylus aiming through flight and ground combat
Marvel's Spider-Man 2
Symbiote and dual-hero combat demands inputs.
Kid Icarus: Uprising leans clearly harder on reads.
Kid Icarus: Uprising
Multiplayer Light vs Dark adds human opposition
Marvel's Spider-Man 2
Enemies scripted, not modeling player.
Kid Icarus: Uprising leans a little harder on variance, though the gap is small.
Kid Icarus: Uprising
Weapon drops are randomised
Marvel's Spider-Man 2
Light open-world randomness.
Kid Icarus: Uprising leans a little harder on optimization, though the gap is small.
Kid Icarus: Uprising
Weapon fusion and intensity-wager risk tuning
Marvel's Spider-Man 2
Expanded skill trees and gadget combos 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.
