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
The original tomb-crawling platformer, a spatial puzzle solved with careful jumps.
Metroid Fusion leans Execution (Practiced Mastery); Tomb Raider 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
Grid-based jumps need deliberate, precise positioning
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
Wildlife and guardians follow 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
First-run trap and secret locations are unknown
Tomb Raider leans a little harder on optimization, though the gap is small.
Metroid Fusion
guided structure still rewards route and pattern knowledge
Tomb Raider
Levels are spatial puzzles with solvable routes
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.
