head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

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

Execution · Practiced Mastery
A co-op adventure that relentlessly cycles through genres, demanding precise execution and partner synchronisation in each new mechanical context.
Prototype 2 leans Execution (Practiced Mastery); Split Fiction 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
Split Fiction
Constant mechanical shifts demand fast adaptation and precise inputs
Split Fiction leans a little harder on reads, though the gap is small.
Prototype 2
Blackwatch and infected never adapt
Split Fiction
Co-op partner coordination involves light social reads
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
Split Fiction
Genre-shifting levels introduce some unknown obstacles per run
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
Split Fiction
Each world's mechanics reward mastering the optimal movement path
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.
