We are updating gate counts for airports for the next version.
For small airports, reducing gates to 2-6 would exacerbate the takeover problem.
You can build your own terminal already.
My thinking about reducing the gates at some airports is that it would give some airlines a reason to exist. As it stands currently, even if you get a foothold at some small airports, the big guys with lots of money can move in and squeeze you out of the market. If an airport had limited gates/slots and a small airline was able to become established there, it would give realistic reasons for airlines to form alliances as well. As it stands currently, any airline that has the cash can serve the tiniest airports because there is so much gate space. In the real world, many airlines have merged, code-shared, or even been bought just because they had established themselves in limited markets, or had gate space that was at a premium. When every small airport has 25 gates (including airports that realistically have only 2-6), the only way to keep the competition out is to buy all 25 gates. I'm not opposed to competition, just stating that a whole dynamic to the airline business is missing when many airports have a disproportionately large amount of gate space.
Regarding the abilitiy to build your own terminal... I am aware of that ability... that is the option that I was referring to.
All said, this is a great game and I don't mean this at all to come across as a complaint... merely one member's suggestions. I think it is awesome that you are polling the members for input, and I thought I would present a point of view that may have not been expressed yet. My thought is this would open additional dynamics to the game, where members would have an opportunity to use an additional level of strategy. Just 2 cents from a fan.
