As an estimate I believe I have spent over 200 hours on TimeSplitters 2 (GC)... Goldeneye (N64) probably follows not far behind. Then on the Wii, Goldeneye at 165 hours and The Conduit at 155 hours. If you add together the original game and the MPTrilogy version of Metroid Prime 3 then that would come 5th with about 90 hours.
