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 narrative RPG that tests knowledge of its philosophical systems and dialogue trees more than any combat skill.

Optimization · Pure Optimization
Solvable team-building progression through an all-new fixed roster.
Planescape: Torment leans Optimization (Pure Optimization); Pokémon White Version leans Optimization (Pure Optimization).
Planescape: Torment leans a little harder on execution, though the gap is small.
Planescape: Torment
Combat is deemphasised; the game is built to be avoided or trivial
Pokémon White Version
Menu battles need no dexterity
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Planescape: Torment
NPCs are scripted personalities; no adaptive opponent exists
Pokémon White Version
Campaign trainers are scripted; competitive play is separate
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Planescape: Torment
Some dialogue outcomes and item discoveries are hidden until explored
Pokémon White Version
All-new Pokémon are unknowns until the dex fills
Pokémon White Version leans a little harder on optimization, though the gap is small.
Planescape: Torment
Stat allocation, dialogue routing and companion management reward system mastery
Pokémon White Version
Fresh type matchups still reduce to solvable team building
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.
