I spent a good part of yesterday messing with it, because it was really neat. I inputed the names of all the major console games around the house I could find, but didn't finish. I haven't put in the names of the dreamcast games, the old SNES console games I shared with my brothers when I lived at home, the PS2/Gamecube games I've sold back, OR the PC games in the big folder on the floor. If I want this to be truely comprehensive, I still have a long way to go.
Still.. I've got 338 games on the list now -..- And these are just ones that I have physically sitting in the house, give or take 5 for cards& sell-backs I remembered to add.
Out of those 338, I still have 230 I've never beaten -..- That's really sad!
If you're curious about the breakdown, here's my page.
Man, that doesn't even count all the time I've spent on WoW and iRO
