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

Execution · Practiced Mastery
A handheld Ratchet & Clank adventure shrunk down for PSP with armour collecting.

Optimization · Practiced Mastery
A narrative action RPG where build planning matters more than reflex execution.
Ratchet & Clank: Size Matters leans Execution (Practiced Mastery); The Witcher 3: Wild Hunt leans Optimization (Practiced Mastery).
Ratchet & Clank: Size Matters leans a little harder on execution, though the gap is small.
Ratchet & Clank: Size Matters
Run-and-gun platforming on PSP controls
The Witcher 3: Wild Hunt
Combat timing matters but generous dodges forgive sloppy play.
The Witcher 3: Wild Hunt leans a little harder on reads, though the gap is small.
Ratchet & Clank: Size Matters
Enemies are scripted
The Witcher 3: Wild Hunt
Enemies use fixed AI behaviours; no adaptation.
The Witcher 3: Wild Hunt leans a little harder on variance, though the gap is small.
Ratchet & Clank: Size Matters
Fixed levels and drops
The Witcher 3: Wild Hunt
Loot rolls and minor combat variance only.
The Witcher 3: Wild Hunt leans a little harder on optimization, though the gap is small.
Ratchet & Clank: Size Matters
Weapon upgrades and armour-set collecting
The Witcher 3: Wild Hunt
Builds, alchemy, and quest routing 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.
