Thanks for all the kind words!
I totally agree with missing flight connections from some other games, that's the original reason I started working on this game hehe . I am thinking of ways to do some better analyzes or prediction when players want to setup new route/evaluate existing route.
More categories to ranking page - Yes for sure! I will consider airline value and profit margin, on top of that i was also thinking of adding passengers per continent etc
World economy more variable - this is doable, but i need to be very careful - i don't want to make the fluctuation of condition become a burden (tweak stuff back and forth) instead of adding more fun
. My longer range goal is to allow airline to invest into airport to affect demand, but it's kinda a long term goal. (and my next expansion space and beyond...kekeke)
Connecting to other countries - Ah i see what u mean, China is still a very good base for hub as international passengers can take domestic flight of china to get to other cities instead of the gateway ones. One thing i could consider is if a country has good relationship with an airline, it might grant it sixth freedom (that's something an airline has to do to gain favor from a country) would be fun to work on...i will see what i can do with that
