Good multiplayer game for husband & wife

[Budo]

I would rent Zack & Wiki.

Although it's not a 2-player game, it's puzzle based so both people can talk out the solutions (99% of the game is puzzle stuff, as opposed to platform jumping, etc.) while looking on screen.

Guitar hero III is always a good choice. can either be competive or co op. and even online.
