what is the length of halo 1,2,3? ?

[dr_dennis]

i want to know the minimum, the maximum and the average length in hours of each game....me and my friend will try to beat them in one go

i dont know about times but i do know that the difficulty goes down so 1 is hardest then 2 then 3 is the easiest if you and your friend are good you could probably beat halo 3 in somewhere around 6 hours but im just guestimating.
