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 four-player Wii Kirby romp gathering ship parts for the stranded alien Magolor.
FAR: Changing Tides leans Optimization (Pure Optimization); Kirby's Return to Dream Land leans Optimization (Practiced Mastery).
Kirby's Return to Dream Land leans a little harder on execution, though the gap is small.
FAR: Changing Tides
Simple swimming, climbing, and sail handling
Kirby's Return to Dream Land
Easygoing main game; EX mode adds modest demands
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
Kirby's Return to Dream Land
Bosses are pattern-scripted
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
FAR: Changing Tides
Set-piece obstacles, little randomness
Kirby's Return to Dream Land
Energy sphere hiding spots are static secrets
FAR: Changing Tides leans a little harder on optimization, though the gap is small.
FAR: Changing Tides
Managing sail, engine, and fuel loops efficiently
Kirby's Return to Dream Land
Super ability timing and sphere collection are 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.
