Anyways there is a lot more to do than recon, baloon bursting and dogfights.
Ground strafing was common, Bombing (for 2 each side needs a 2 seater for bombing missions), Artillery directing, fighter scrambles (which are a bit like dogfighting but one side will start on a airfield and have to get altitude to stop the other sides bombing or recon mission).
We play one game every month from Verdun to the end of the war. We also spend a lot of work about which plane that comes in when and have some custom rules for modified planes, like for adding a Lewis gun to your Nieuport 17 (who already have a vickers), changing your DRI engine to a Le Rhone, Getting a BMW engine to you Fokker DVII (Making it a DVII/F), getting a Sopwith Triplane with 2 vickers instead of one and so on.
Every player do gets to borrow a planr from me, we started with DH2, Nieuport 11 and Fokker EIII. People who own their own planes can play with them as soon as they enter the war. The old planes with be changed out when they did in the real War, we are playing today and the german default plane will change to a Albatross DII (or a Roland, we have gotten a lot of players now). I also have a bunch of planes that the sides can borrow one month (usually the month before it officially hit the front in numbers, for revaluation). Of course there is extra xp to get a plane that is under evaluation.
Well, enough from me now, have to turn in, we start todays game in 7 hours
