Games I own
A very comprehensive list of the physical games I own is at IGN. And the fun stats page showing breakdown per platform.
My Virtual Console/WiiWare/DSiWare games can be found on the overloaded My Virtual Console Games page.
Listing of my digital downloads in general (including PSN/XBLA/Steam/whatever) at Backloggery, but it is severely out of date as of this writing.
