Metroid Fusion or Metroid Zero Mission?

[KentaRawr!]

A short while ago, I got Metroid Prime and a Controller for $13.20, and I had enough money left over to get a used GBA Game. I decided I would get a Metroid Game. But, there are 2 Metroid Games for the GBA. Metroid Fusion and Metroid Zero Mission. I saw a Video of Metroid Zero Mission, and it looks great! But I saw a few Pictures of Metroid Fusion, and it looks really good too. I heard that Zero Mission is short, but I have also heard that Fusion is quite Linear.

So, I was wondering...

Metroid Fusion or Metroid Zero Mission?


Here is a Video of Metroid: Zero Mission. Couldn't find one for Metroid Fusion.

Edit: Since my Sister said I should get Fusion, I voted "Metroid Fusion".
