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 · Pure Optimization
A classic-styled JRPG whose brave/default system turns turns themselves into a resource.

Optimization · Pure Optimization
Character-driven turn-based JRPG with a deeply customizable orbment magic system.
Bravely Default leans Optimization (Pure Optimization); The Legend of Heroes: Trails in the Sky leans Optimization (Pure Optimization).
The Legend of Heroes: Trails in the Sky leans a little harder on execution, though the gap is small.
Bravely Default
Turn-based menus; no physical demands
The Legend of Heroes: Trails in the Sky
Turn-based menus only
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Bravely Default
Bosses follow fixed scripts
The Legend of Heroes: Trails in the Sky
Scripted encounters, no adaptation
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Bravely Default
Minor drop and encounter randomness
The Legend of Heroes: Trails in the Sky
Minor turn-order and drop randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Bravely Default
Job combos and brave/default economy are deeply solvable
The Legend of Heroes: Trails in the Sky
Orbment quartz setups and turn-bonus manipulation
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.
