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 · Pure Optimization
Meditative sequel sailing and diving a hybrid ship through flooded ruins.

Optimization · Practiced Mastery
A meditative climbing adventure ascending a vast dried-out seaside tower.
FAR: Changing Tides leans Optimization (Pure Optimization); Jusant leans Optimization (Practiced Mastery).
Jusant leans a little harder on execution, though the gap is small.
FAR: Changing Tides
Simple swimming, climbing, and sail handling
Jusant
Deliberate trigger-grip climbing, stamina not twitch
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
FAR: Changing Tides
Solo voyage with no adaptive opposition
Jusant
No opposition on the tower
FAR: Changing Tides leans a little harder on variance, though the gap is small.
FAR: Changing Tides
Set-piece obstacles, little randomness
Jusant
Routes are fixed and readable
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
FAR: Changing Tides
Managing sail, engine, and fuel loops efficiently
Jusant
Reading the wall and planning pitons is the game
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.
