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

Execution · Practiced Mastery
Remake of the original Metroid with modern movement and a stealth epilogue.

Optimization · Practiced Mastery
A rhythm-strategy game commanding tribal warriors through drumbeat commands.
Metroid: Zero Mission leans Execution (Practiced Mastery); Patapon Remastered leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Metroid: Zero Mission
polished 2D movement plus a stealth finale
Patapon Remastered
Rhythm-timing inputs are the core execution challenge.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Metroid: Zero Mission
enemies and pirates are scripted
Patapon Remastered
No adaptive opponent, scripted enemy encounters.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Metroid: Zero Mission
hidden passages unknown only once
Patapon Remastered
Some randomized loot and item drops.
Patapon Remastered leans a little harder on optimization, though the gap is small.
Metroid: Zero Mission
sequence breaks and route optimization are celebrated
Patapon Remastered
Unit composition and rhythm-command strategy are deeply 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.
