Most of the console games I've played at least a little bit, but then they got put on the backburner for something else. Probably something like 75% of the PC games I haven't even loaded up yet, with many of them still uninstalled.
Just Cause 2, GeoW2, Demon's Souls, and Dragon Age are between 50% and 90% complete, so they can be kind of disregarded. Currently playing inFamous (started 2 days ago, 50% complete). And I've only listed games I plan to beat, and some plan to 100%. Games I don't care to play again were left off the list.
