head to head
Planescape: Torment asks more than The Council, and the gap is optimization.

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

Optimization · Systems & Chaos
A social-intrigue RPG where you spend skill resources to exploit dinner guests' scripted psychological weaknesses.
Planescape: Torment leans Optimization (Pure Optimization); The Council leans Optimization (Systems & Chaos).
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
The Council
Menu-driven confrontations; 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
The Council
NPCs have vulnerabilities and immunities, but fully scripted.
The Council leans a little harder on variance, though the gap is small.
Planescape: Torment
Some dialogue outcomes and item discoveries are hidden until explored
The Council
Hidden character traits and unknown consequences until learned.
Planescape: Torment leans clearly harder on optimization.
Planescape: Torment
Stat allocation, dialogue routing and companion management reward system mastery
The Council
Skill points, effort resources and exploiting known weaknesses are systemic.
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.
