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
Dodging scripted bullet patterns while solving each fight's pacifist logic.
Bastion leans Optimization (Practiced Mastery); Deltarune 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.
Deltarune
Bullet-hell dodging in battles demands real reflexes
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.
Deltarune
Enemy patterns are charming but fully scripted
Bastion leans a little harder on variance, though the gap is small.
Bastion
Minor loot variance.
Deltarune
Encounters and secrets are fixed once known
Bastion leans a little harder on optimization, though the gap is small.
Bastion
Weapon and idol builds reward planning.
Deltarune
ACT routes, sparing logic and TP economy are solvable
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.
