Most played game this year is Mario Kart Wii:- 215 hours 8 minutes.
Incidentally I am not sure I have played many games more than that in total ever, MK 64 is probably close. Windwaker and TimeSplitters 2 are probably about the same amount of time.
Maybe Banjo-Tooie? not sure about that... the 3 save files add up to 130 hours but I am sure I have deleted some before.
