I genuinely think the mobile community would be over the moon if we got a couple of other regions. I don't know what is coming but assuming the current regions already have the majority of main airports, just adding more within those relative confines would be a little disappointing. NY or Vegas would be a bonus and would love to see some other possible locations such as the Caribbean, UK etc.
Two of the competition are now offering global scenery but the quality for me just isn't close to Aerofly and I much prefer the single purchase approach instead of subscriptions or microtransactions with the exception of IAPs for main region options.
