head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

Optimization · Pure Optimization
A base-layout and attack-planning puzzle against static player defenses.

Optimization · Pure Optimization
A narrative RPG that tests knowledge of its philosophical systems and dialogue trees more than any combat skill.
Boom Beach leans Optimization (Pure Optimization); Planescape: Torment leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Boom Beach
Tapping troop deployments takes no dexterity
Planescape: Torment
Combat is deemphasised; the game is built to be avoided or trivial
Boom Beach leans a little harder on reads, though the gap is small.
Boom Beach
Attacks hit static bases - defenders aren't present to adapt
Planescape: Torment
NPCs are scripted personalities; no adaptive opponent exists
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Boom Beach
Scouting reveals most info; matchmaking adds some spread
Planescape: Torment
Some dialogue outcomes and item discoveries are hidden until explored
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Boom Beach
Base layouts, troop compositions and timing are the solvable core
Planescape: Torment
Stat allocation, dialogue routing and companion management reward system mastery
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.
