head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Practiced Mastery
Two Spider-Men, faster traversal, and deeper combo systems.

Execution · Practiced Mastery
A black-and-white cinematic samurai side-scroller built on parry-timing duels.
Marvel's Spider-Man 2 leans Execution (Practiced Mastery); Trek to Yomi 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's Spider-Man 2
Symbiote and dual-hero combat demands inputs.
Trek to Yomi
Parry and counter timing carries every duel
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Marvel's Spider-Man 2
Enemies scripted, not modeling player.
Trek to Yomi
Enemies follow scripted attack patterns
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Marvel's Spider-Man 2
Light open-world randomness.
Trek to Yomi
Linear cinematic encounters, nothing hidden
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Marvel's Spider-Man 2
Expanded skill trees and gadget combos solvable.
Trek to Yomi
Learning combos and enemy patterns is 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.
