How long did it take you to complete Halo 2?

I have seen a lot of Halo gamers who are very fast with completing their Halo games 100%. For those who played Halo 2, how long did it took you to complete it? Tbvh, I never completed mine.

I never completed mine, I played for a period of time and then completely abandoned it for a new game ( I do this a lot to be honest).

It took me about 10 hours to complete Halo 2 main story. But when I went for 100% completion, it took me about 21 hours. It's a very good game to the best of my knowledge.
