Christ, I hope my wife doesn't see this...
I probably spent about $2k in gaming in 2007. And that's a conservative estimate.
Rock Band
Xbox 360 (early in year)
~15 games
Guitar Hero III
PSP
PS3 used
10 months of Gamefly
... and I'm probably forgetting other stuff.
This year, it looks like a new gaming rig might be in order. That's another $500-1000 easily.
