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.

Execution · Practiced Mastery
Tense, linear Metroid hunted through a station by a clone of yourself.

Optimization · Practiced Mastery
A trap-heavy sequel where level knowledge beats reflexes.
Metroid Fusion leans Execution (Practiced Mastery); Tomb Raider II leans Optimization (Practiced Mastery).
Metroid Fusion leans a little harder on execution, though the gap is small.
Metroid Fusion
demanding bosses for a 2D Metroid
Tomb Raider II
Precise platforming plus more frequent gunplay
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Metroid Fusion
SA-X stalking runs on fixed scripts
Tomb Raider II
Human enemies still run fixed scripts
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Metroid Fusion
first-encounter dread fades once mapped
Tomb Raider II
Unknown traps and ambushes punish first runs
Tomb Raider II leans a little harder on optimization, though the gap is small.
Metroid Fusion
guided structure still rewards route and pattern knowledge
Tomb Raider II
Route, key-item, and secret solving dominate
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.
