I was just here sorting out my system to get it ready for this game when I saw this thread.
Since you're all looking at playing it this is what I'm getting ready for......its a big organised battle tour of duty based on arma....
http://www.armainteractive.com/
Which is being run by some friends of mine in the US and America. It has proper rank structures, and armies, divisions, battlions and so forth.
Not little kids, mostly good blokes. full TS etc. At the moment they're doing tactics runthrough using ofp to get ready....they take it pretty seriously.
ie You can ground pound or if you like tanks you can be a tanker, - if you fly well you can try out for AVN.
There are two armies (obviously) Russian and US - you can try out for either.
I think they're going to do a beta tour soon which will be v cheap or free to work out the kinks.....as soon as the US version becomes available.
But there are guys on there now using the czech and german versions and patching them to english.
Its being run by a bunch of blokes who played BF2C. Highly structured. No noobs, smacktards or idiots and a few military guys keeping us all in order
I'm in the 501 Parachute (Airbourne) though most brits seem to be going to the russian side!
Have a look at the forums and see what you think. Should be cool.
Personally for me I like playing with these guys over pub servers, since they have pilots that can drop me right on the action. With maps like that....haha, you'll need it.
Good luck and if you sign in tell them HandsomeSOB sent you. They'll love that hahaha.
