Does everyone realize that this is probably the timer bug, right?
No idea what you mean.
Neverwinter Nights - Heavy RP Permanent Worlds Tolkien's background - some 2 years. Didn't count but I bet it means lots of hours.
Morrowind/Oblivion/Skyrim - over 2,000 hrs each - Because there were nothing better to play
ME1/2/3 - so many replays with different Shepards...
Dragon Age Origins - over 2,000 hours, over 20 different characters with around 100 hours each - More to come.
TW1 and TW2 - can't really say but I've replayed them so many time and will do so again so much...
TW3 - About 1,700 hours - Galaxy clocks all my 13 playthroughs - In game clocks on that particular run - I have all my end game save files saved. If I reload them and do the math with each one I am certain that the total will be a match.
