Last year was not normal since I bought both a 360 and a Wii. That's $650 (tax-free where I live).
5 new 360 games and 1 used =$340
3 new Wii Games = $150
A butt load of DS games I don't feel like adding up right now, but I'm going to estimate $1300 when added.
I've purchased 1 360, 1 Wii, 2 DS games so far this year, so I say $700 is a good yearly average for me.
