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
An open-world revenge tale where a new shapeshifter hunts Alex Mercer through plague-zoned New York.

Execution · Practiced Mastery
id Software's post-apocalyptic shooter mixing crisp gunplay with buggy racing.
Prototype 2 leans Execution (Practiced Mastery); Rage 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.
Prototype 2
Power-swapping combat and traversal demand decent dexterity
Rage
id-style gunplay precision against agile bandits.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Prototype 2
Blackwatch and infected never adapt
Rage
Enemy mobility is scripted animation, not adaptation.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Prototype 2
Sandbox encounters carry slight randomness
Rage
First-run unknowns in dungeons and loot.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Prototype 2
Mutation upgrades and target-hunting routes reward planning
Rage
Crafting, ammo economy, and wingstick usage reward planning.
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.
