I think it's a great mod, very realistic!
some people might find it difficult to play and quit very soon, because at the first times you get kill and you can't tell who shot you and from where, I have few friends that did that.
It is difficult because it isn't based on aiming and reaction skills, they sure take a part but the skills that really matter are strategy and tactics, and most important thing in the game is teamwork! A team with good leadership and players with discipline can win in no time! but to reach such a status it take to have an organized group/clan.
I suggest trying this game, and don't give up too soon if you get owned!
