So, SM has given into the demands of his gf for 2 player gaming, and is now considering purchasing a console or 2...

Since this is to be my first console purchase since the MegaDrive, I need input:

Here are my current selections:

Nintendo Wii: Pretty much in, as the woman likes the sports, Michael Jackson, and the whole 'wave-your-arms-about-as-a-possessed-person' aspect of this. So what I need is game suggestions for this that would make it palatable for me. Also some other 2 player games would be nice. My MJ moves are despicable.

Xbox 360/PS3: One of these should be in for me to retain my sanity. Decision will be made on availability of fighting games (the tekkens for example, or dragon ball), and guitar hero/rock band. Also please recommend any other 2 player games that are not strategy or split-screen (hate split-screen).

As I'm keeping my PC for strategy/1 player shooters, that's not an issue.

Are there any consoles on the horizon I should hold out for?

If there are any other recommendations I will be glad to hear them!

Cheers!
