What bugs me is when countries 1 and 2 can be at, say, 130 and 110, respectively, while country 3 has 70, and ONLY country 1 gets slammed by ENY because they're the high number of players.
While I understand the concept, I think the execution still needs work. I think a more dynamic setup than there already is is necessary, where ENY restrictions are based more on the local theater.
Or alternately, one I've heard suggested, is that ENY doesn't eliminate flyable planes, but rather drastically increases the perk price of ones that are already perked, and makes planes that otherwise would be blocked out INTO perked rides (sufficiently perked so that people actually feel it).
