Good point. I hadn't really thought about all the new planes that have come since beta. Allowing all of those would be a mistake. Certainly the jet and rocket would be a negative.
So yah, I think you have a good point. Either just go with the original limited plane set..... there was no lack of fun or good fights with that... or have one of the rational minds select 3-4 small more or less "matched" plane sets that would rotate, perhaps daily.
I think we could use that exact map; there was a certain atmosphere to crossing the ridge line and entering "Injun country" that I find lacking in the new maps that have no definitive proprietary boundaries.
It wouldn't hurt to put a bit of rolling terrain into it though. Not the real deep canyons but some ridges, hills and canyons that provide another aspect to the low vertical fights.
Good suggestions.
