Well I am not a professional player, I work 50 hours a week, so I try to play an hour each night and maybe 2 to 4 on the weekends. I got the game on release date and as of 2/14/09 I am on my second prestiege a level 61 (almost at 3rd.) and have played (game time) 6 days and 18 hours.
I play alot od mercanary team death match, team death match as well as search and destroy and capture the flag. I have heard a lot of people rank up fast playing headquarters, I am not a big fan of headquarters, but have played it a few times and did get lots of xp points.

As for classes, I am a big fan of the mp40, round drum,with stopping power and steady aim, and have another class set up with mp40, round drum extreme conditioning, deep impact.

I got the game the morning it came out and play it at least an hour a day, sometimes up to 6 a day if I have the time. I am currently on level 44 on my 5th prestige. Its January 12 now which means I’ve been playing for 2 months and 1 day. I’ve seen SOOOOO many people on level 65 or their 10th prestige which either means they have no life whatsoever or are using the accelerator hack I’ve read about. I think it should take any normal person with a social life 2-3 weeks to prestige.

On a side note. For anyone else who was dumbfounded at the lack of a music volume control in Call of Duty 4, I am pleased to have learned (rather then the assumption I previously had) that Call of Duty 5 DOES have this control. Its nice to hear everything without music.
