I'm not a fan of FPS games but I recently got into Halo 1 on my 360 and really, really, really enjoyed it.  It was linear which some people dislike, but for me a bonus.  Now, onto my question:

I didn't play MP1 or 2 on the Cube though I do have a cube.  I played Metroid on my DS and hated it.  Controls and shooting were not what I would call optimal.

What kind of game is Metroid, really?  Is it esentially a FPS?  Can you compare any or all of the Metroid Prime series 2 on cube and upcoming Wii with the Halo 1 style of gameplay?

I've avoided the Wii until now due to my disappointment with the graphics engine, but I'm looking at MP3 and thinking hmmmm....

Hunters, Halo, and the Prime series don't control similarly at all. On top of that, Corruption doesn't control similarly to the other two Prime games. The first two weren't exactly FPSs in the traditional, action-oriented sense of the term, but it seems like Retro increased the pacing and the number of enemies on screen at any given time.

As I expect Corruption to be much better than the first two, and I consider the original Prime to be enough reason to buy a system, I'd say yes. Wait for a couple reviews, though.

Well, theres a ton of better reasons to buy a wii but I guess MP3 is a good reason. Don't be a fool and get a system for only one game though. Look at its other games first and see if you like any of them. Then make your decision.

I'm surprised you avoided the Wii for only one reason, just cause of the graphics? Thats not a good excuse.

Its hard to say... the game is not out yet...

Is it enough? Yeah, it will be a long game, and worth looking into.

I played the metroid games to gamecube, I enjoyed the first game very much, didn't like the second though.
I look at metroid prime 3 and I see everything I liked with the first game:P

No. (as buying a console for one title is somewhat silly unless you REALLY REALLY want that game, but sounds like you are unsure.) but Twilight Princess, Mario Galaxy, Metroid Prime 3, and Smash Brothers Brawl are enough reason to buy the Wii. And even if you don't like all those genres, you should still give them a try because they aren't "traditional" and will all be awesome with Twilight Princess being the runt of the litter. XD

And there's also Mario Kart Wii, Trauma Center, Wii Fit, countless past gen titles, new control scheme, low price, and does the Wii have free online?

It was for me. However the definative game that got me to get a Wii is still a long ways off. Mario Kart baby!

Yes. I would think so as it's the reason I bought mine.

I guess TP, SMG and SSBB and the VC do help tilt the scale even more in favor of a Wii purchase but Metroid is the game I mostly look forward to.
