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

Optimization · Pure Optimization
Quiet side-scrolling journey piloting a land-ship across a dried-out sea.

Optimization · Pure Optimization
Reasoning through fixed adventure-logic puzzles inside a sci-fi story.
FAR: Lone Sails leans Optimization (Pure Optimization); The Fall 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.
FAR: Lone Sails
Light platforming and timely lever pulls
The Fall
Light combat and platforming pose little physical test
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
FAR: Lone Sails
No opponent of any kind
The Fall
Story AI characters are fully scripted
The Fall leans a little harder on variance, though the gap is small.
FAR: Lone Sails
Mostly fixed obstacles, minor unknowns first run
The Fall
Puzzle solutions are hidden until reasoned out
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
FAR: Lone Sails
Fuel management and ship-routine efficiency are the game
The Fall
Adventure-logic puzzles each have one intended answer
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.
