I think the game could do with random events which could give it a nice challenge and help break up the repetitiveness and predictability.
There are a number of things that happen in the real world that could spice the game up a bit:
Destinations closing due to bad weather or other situation.
The airport you are playing (assuming you’ve unlocked at least 2) closing due to bad weather, or maybe only aircraft of a certain size can still get out.
Aircraft returning back to your airport for a medical emergency, costing you more to service the plane again.
Flights being diverted to another airport. Not only delaying the plane getting to it’s destination but costing you more.
Flight stuck at the gate due to the flight crew being missing or delayed waiting for passengers.
Arrivals interrupted for an emergency landing.
Some sort of emergency forcing a taxiway or the runway to close - that could be linked to a mini-game to deal with the situation.
Some of these would clearly be a lot easier than others to implement!!
I’d suggest a global pandemic grounding flights around the world and reducing them by 50% or more but that just seems unrealistic…
I feel isn’t suggestions 1-4 a bit infuriating as it could affect player connections and damage the games already not too great reputation?.. since it kind of forces people to purchase in-game items more often.
Oh, I hadn’t realised the game had a bad reputation.
I’m not sure any of my suggestions them would force you to purchase more in-game items, that’s really just down to how impatient you are I guess.
I just feel that once you figure out the right way to expand an airport (which you learn pretty quickly playing INN) there isn’t much of a challenge. You could complete any achievement with any size fleet, it’s just a matter of time; you always make money, not matter what you do there isn’t really a way to lose. You can reset an airport to start again but that is because you want to try something different; you don’t need to reset and try again because your choices mean you just can’t beat that that level.
Before was more ground aligning of the plane ( the small guys with illuminating sticks in hands) but now no more.
I have one it 500hours in-play.
Such a shame
