@Words Of Wisdom,

Metroid Prime: Hunters has a multiplayer portion. So does Metroid Prime: Echoes. Just mentioning those games makes me want a Metroid Prime: Hunters game for the Wii.

 From playing the games I have a pretty good sense of Samus's character. Samus is essentially Batman recast in a scifi setting.

 She was orphaned at a young age by a space pirate attack and adopted by the Chozo who trained her and infused her with their blood. She uses a suit of Chozo armor adapted for human use and can incorporate a myriad of devices of Chozo, Galactic Federation, Space Pirate, and other origins into it. She designs her own ships and is extremely skilled at gaining access to secured computer systems. She's a stoic loner who is both skilled and resourceful enough to defeat any opponent.

 I generally don't engage in this sort of fanboy frothing but she's in my top four heroes of all time. The other three are Paul Erdos, Charlie Parker, and Optimus Prime.

It was to be expected. Even Halo fanboys drool over Samus. She always wins in showdowns with other girls of gaming too. No contest.

Btw, you know how the other contests are going to end. Batman vs Iron Man? Common..

Two Metroid games I have yet to play (I own almost all of them including the NES ones...).  Hunters I may pass on but I'll be playing Echoes soon enough.

 I must confess I wouldn't mind seeing an objective based (defend/destroy the generator, defend/capture the command center, etc.) multiplayer Metroid with a Galactic Federation team lead by a randomly selected player as Samus versus a Space Pirate team with a randomly selected player as a pirate commander. You could still incorporate elements of traditional Metroid gameplay by incorporating each team's leader's special abilities into the objectives so that each team has to support their leader in order to achieve their objective.

Echoes multiplayer was not worthy of mention, while Hunters multi was intence, but the game DIDN'T HAD ANY METROIDS! The could have called it Samus Adventure as well. Samus is far better on her own. 

 The increasing difficulty the writers will face in incorporating Metroids into future games has me a little worried about the series.

We'll see where the next adventure takes her.  I don't think it'll be too difficult for the writers.  There are all kinds of unused plot gimicks to fall back upon in a worst case scenario such as time travel and the like to really worry about the story.
