The first week is probably going to be nothing more than a mad deathmatch of people exploring and checking out the immense world of PS. Once the initial shock wears off, then you'll start to see more organization and teamwork. The very reason PS is unlike any other FPS is because you CANNOT just jump into the game day 1, and experience everything it has to offer. You need to get your bearings, and develop your character as suited to your skills and interest.
I'm rather sick of this "waah waah, I want everything the game has to offer immediately because I'm impatient and I like to use cheats in singleplayer games because I want everything blah blah." Get over yourself
