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
Sandbox FPS where a nanosuit lets you choose speed, strength, or stealth per fight.

Execution · Practiced Mastery
Sprawling action horror with four campaigns and a surprisingly deep combat system.
Crysis leans Execution (Practiced Mastery); Resident Evil 6 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.
Crysis
gunplay and suit-mode switching mid-fight
Resident Evil 6
Deep melee-and-gunplay movement system rewards mechanics
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Crysis
AI soldiers are scripted searchers
Resident Evil 6
Agent Hunt PvP adds a sliver of prediction
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Crysis
open encounters play out unpredictably at first
Resident Evil 6
Set-piece campaigns are fixed after first sight
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Crysis
suit energy management and approach planning
Resident Evil 6
Skill builds and Mercenaries combos are learnable
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.
