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
A forgiving licensed romp testing basic platforming and light puzzle solving.

Execution · Practiced Mastery
The PlayStation Vita Uncharted, a portable cinematic treasure hunt with touch controls.
Shrek 2 leans Execution (Practiced Mastery); Uncharted: Golden Abyss 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.
Shrek 2
Light platforming and enemy bashing with forgiving timing
Uncharted: Golden Abyss
Touch-assisted gunplay and climbing, gentler demands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Shrek 2
Scripted movie-tie-in enemies never adapt to you
Uncharted: Golden Abyss
Scripted enemy encounters only
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Shrek 2
Levels and puzzles are fixed once seen
Uncharted: Golden Abyss
Linear handheld adventure
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Shrek 2
Simple puzzle solutions and character-swap routing to learn
Uncharted: Golden Abyss
Collectible hunting and encounter knowledge
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.
