The A v A, because of it's very Axis v Allied nature almost always dictates that one side has the Boom and Zooms and the other the Turn and Burns. As a result I rarely see what I personally am looking for in there.
The "come one, come all, run what you brung" basic freewheeling furball.
I think having most of the plane set available adds variety. Last night the players favored the FM2, the Zeke, an early Jug, a 109F, SpitV, C202, P40 and the like. Both sides having access to all, of course.
The less "rules" the better. Basically, we just decided to fight 1 v 1 (because there weren't all that many of us), start at 5k, first merge cold nose. That was it.
If we can get more people in there we can do multi v multi and if we 20+ we can just go with Early-Mid war and a 5 or 10k ceiling and let it rock.
It sure beat the heck out of Timidinao as it was playing last night. Guaranteed good fights, no waiting, every single time.
