I believe that in this world you can do almost everything
Let's start with the fact that you could see the countryside in a different way from how it was done now.
Meanwhile, the duration ...
Why not make it an annual / biennial / triennial?
It will be unique because it is the real country with clear rules and defined, which really takes a lot of importance to arrive safely at the end of the fight, and where some rash unless you go with more attention to do the fighting fronts ... In short, everything would take more sicuamente value and importance ...
Where every important date is activated the map on which you should collide ...
Obviously with the restriction of aircraft available to choice ...
Then that will be slaughtered for poloti semplcemente you can add a small change ...
example:
Pandolo is killed, the next scenario in flight if I sign obviously there will pandolo 2 ° (a bit 'like a pandolo junior) and so on for the other killing.
Again I ask your pardon for my english ...
