Which lasts longer, Metroid Prime 3 or Bioshock?

Question

I have $50 coming soon, and I'm trying do decide between Metroid Prime 3: Corruption or Bioshock. Which one lasts longer?

Answer 1

metroid 3 is maginally longer, but you won't play it to the end because of complete boredom (the game music will drive you insane if the tedious gameplay doesnt)

bioshock's a brilliant shooter, slightly shorter, but there's a h**l of a lot to do and every aspect of the game is thought about, giving a better gaming experience

Answer 2

bioshock is for wii? get it!

Answer 3

Bioshock has more gameplay (making it "last longer") and is a far better game.
