Okay, I'm having a little bit of a .... gaming dilema.
A wii gaming dilema.
I have the opportunity to buy one game, any game, and I have decided on two options.
It is between
Super Mario Galaxy
or
Metroid Prime 3: Corruption

The only thing is, I used to own Super Mario Galaxy but I lost it a year ago, and I was very far in the game.

Should I buy another Super Mario Galaxy?
or
Should I buy Metroid, which I have never played before...

help please, what should I do.

I posted this question here since I figure most, if not all newgrounders are gamers, so they would be able to help me out..
