I'm not much of a gamer but like to rock guitar hero with the kids. (as you know steve)
Haven't played it yet but i got GH Metallica from a $15 bin for christmas and gave it to myself under the tree.
My kids are mainly into the LEGO series of games which would be the only things i guess i could recommend to anyone. The Batman, Indians Jones, and Pirates of the Caribbean seem to be huge hits if you got kids.
