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 · Systems & Chaos
Spaceship roguelike of crew management and desperate sector hops.

Optimization · Pure Optimization
A theorycraft-dense ARPG about engineering builds through randomised loot and crafting.
FTL: Faster Than Light leans Optimization (Systems & Chaos); Path of Exile leans Optimization (Pure Optimization).
Path of Exile leans a little harder on execution, though the gap is small.
FTL: Faster Than Light
Pause-and-play tactics, no input precision.
Path of Exile
Some dodge and reflex play, but build carries fights.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
FTL: Faster Than Light
Scripted enemy ship AI.
Path of Exile
Mobs and bosses are scripted; no adaptation.
FTL: Faster Than Light leans a little harder on variance, though the gap is small.
FTL: Faster Than Light
Sector events and shop rolls drive runs.
Path of Exile
Loot, map mods, and crafting outcomes are heavily random.
Path of Exile leans a little harder on optimization, though the gap is small.
FTL: Faster Than Light
Power management and ship builds are deeply solvable.
Path of Exile
Passive tree, crafting, and economy form near-infinite theorycraft.
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.
