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 · Systems & Chaos
A colony sim where the storyteller's randomness tests your designed defenses.
FTL: Faster Than Light leans Optimization (Systems & Chaos); RimWorld leans Optimization (Systems & Chaos).
FTL: Faster Than Light leans a little harder on execution, though the gap is small.
FTL: Faster Than Light
Pause-and-play tactics, no input precision.
RimWorld
Pausable, no input precision required.
RimWorld leans a little harder on reads, though the gap is small.
FTL: Faster Than Light
Scripted enemy ship AI.
RimWorld
Storyteller AI is randomised, not adaptive to you.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
FTL: Faster Than Light
Sector events and shop rolls drive runs.
RimWorld
Raids, weather, and pawn traits are heavily random.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
FTL: Faster Than Light
Power management and ship builds are deeply solvable.
RimWorld
Colony layout, work priorities, and defenses solvable.
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.
