Axis vs Allies (originally called "Combat Theater") differences with the MA:
1. 2 sides with one side featuring a limited Axis plane set and the other a limited Allied plane set and the terrain often being historic.
2. Numbers.
This arena has tried almost everything to build numbers:
1. It has offered perk planes for free.
2. It has tried creative alternate history set-ups for balance.
3. It has promoted a 'civil gentlemen pilot environment' that differs from the typical MA environment (though I think that's neither
necessary nor beneficial since it often comes across as shaming or 'manners policing' the player population to no good effect).
4. There have even been rare occasions (iirc) that the AvA pretty much hosted a mini 2-sided MA with all Axis planes vs all Allied planes.
(I could be wrong. My memory is less 'perfect' than before.)
The most I remember ever logging into the AvA was still less than 40 (with the MA pushing almost max pop).
What difference .... is going to make a difference? (Bear in mind that I was once CT staff and I promoted that arena with all of my energy.)
