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

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

Optimization · Practiced Mastery
The systems-heavy sequel where the journey itself is the danger.
Bastion leans Optimization (Practiced Mastery); Dragon's Dogma 2 leans Optimization (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.
Dragon's Dogma 2
Physical combat and monster climbing demand handling
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.
Dragon's Dogma 2
Scripted monster ecology, no adaptation
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Bastion
Minor loot variance.
Dragon's Dogma 2
Emergent travel encounters surprise until learned
Dragon's Dogma 2 leans a little harder on optimization, though the gap is small.
Bastion
Weapon and idol builds reward planning.
Dragon's Dogma 2
Vocation builds and pawn logistics reward mastery
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.
