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

Optimization · Practiced Mastery
An isometric action RPG narrated as you play.

Execution · Practiced Mastery
Sumi-e Zelda-like where a wolf goddess paints the world back to life.
Bastion leans Optimization (Practiced Mastery); Okami 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.
Bastion
Action combat needs timing and aim.
Okami
Brush strokes and combat timing, forgiving
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Bastion
Enemies are scripted.
Okami
Demons follow fixed patterns
Bastion leans a little harder on variance, though the gap is small.
Bastion
Minor loot variance.
Okami
Authored world with no randomness
Bastion leans a little harder on optimization, though the gap is small.
Bastion
Weapon and idol builds reward planning.
Okami
Brush technique use, upgrades, and exploration
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.
