head to head
Metroid Prime Hunters asks more than Grand Theft Auto: San Andreas, and the gap is reads.

Optimization · Practiced Mastery
A sprawling open-world crime epic with RPG-style character stats across a whole state.

Execution · Practiced Mastery
A DS first-person shooter pairing a Metroid campaign with surprisingly competitive online deathmatch.
Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery); Metroid Prime Hunters leans Execution (Practiced Mastery).
Metroid Prime Hunters leans clearly harder on execution.
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Metroid Prime Hunters
Stylus aiming on DS is a real physical ceiling
Metroid Prime Hunters leans clearly harder on reads.
Grand Theft Auto: San Andreas
Gang AI is scripted, never adaptive
Metroid Prime Hunters
Online deathmatch rewards out-predicting human hunters
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto: San Andreas
Territory wars and traffic add light randomness
Metroid Prime Hunters
Maps and pickups are fixed
Grand Theft Auto: San Andreas leans a little harder on optimization, though the gap is small.
Grand Theft Auto: San Andreas
Stats, gym, weapon skill, and routes reward systematic play
Metroid Prime Hunters
Hunter matchups, map control, and pickup timing
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.
