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.

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

Execution · Practiced Mastery
Rhythm-infused action game of rock duo versus EDM empire boss fights.
Bastion leans Optimization (Practiced Mastery); No Straight Roads leans Execution (Practiced Mastery).
No Straight Roads leans a little harder on execution, though the gap is small.
Bastion
Action combat needs timing and aim.
No Straight Roads
Dodging and attacking on the musical beat
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.
No Straight Roads
Bosses follow rhythm-locked scripts
Bastion leans a little harder on variance, though the gap is small.
Bastion
Minor loot variance.
No Straight Roads
Patterns are fixed to the soundtrack
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Bastion
Weapon and idol builds reward planning.
No Straight Roads
Learning each boss's beat-mapped moveset
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.
