Metroid Primes were way too ahead of my brains, so I just ended up going as far as I can and ditching the game in the end. Yes, played all three on their original consoles (aka no Metroid Prime Trilogy used).
Though Metroid Prime Hunters' focus is on multiplayer shooting, I still suck at it, but that is because I suck at shooters.
Want some real brain busting? Metroid Prime is a game for you, I say.
