It took me a whole 12 or so hours my first time. I got my Xbox and Halo on the Christmas of 2005 at around 8:00 A.M., and around 8:00 P.M. I was finished with Halo.
If I hadn't have kept on going around in circles on the Silent Cartographer and kept on getting killed after you see Captain Keyes all eaten by the flood, I could've gotten it done quicker. ;)
