Hey Bob, congratz.
A very good family game is the "Rockband" family. My daughters 8 and 11 love it, and actually all 4 of us can play. Go find a used set, lots online at kijiji et al for around $80.00
I myself am hooked on the Call of Duty franchise, but it's a FPS..... Rather arcadey though. Nov 9 Black Ops comes out.
Good choice on the 3 btw, If and when 3d ever takes off, you already have a 3d capable player. Sony is going to push that tech hard in the next couple years.
