Zero Mission. it was a great remake of Metroid 1, and i liked the bonus mission they threw in. plus, it was portable. i mean, seriously, that's all you need right there.
I got my propaganda, I got revisionism.
I got my violence in high-def ultra-realism.
All a part of this great nation.
1) Metroid II
2) Super Metroid
3) Metroid Prime
4) Metroid Fusion
5) Metroid
I haven't played enough of Prime 2 or Zero Mission to decide where they fit in my list. They've all been really good though, I look forward to see what they do in the future (besides Metroid Pinball)...
