But I still think that:
How about the following:
Create a start list with all kinds of old aircraft.
This could be props or jets. Min age for props 5yrs,min age for jets 10.
Start with 10million buy as many aircraft as you like (in the rangefrom 3 to 10million).
But you need to have money left to buy gates and start a route.
The way I look at it the older aircraft have higher operating and fuelcost levelling out the "advantage" you have on buying a cheaper airframe.
To refrain the 2ndhand market to be overwhelmed with old aircraft these could automaticly be mothballed after 4/5 years of gameplay.
This also cuts out on speculating with 2hand start aircraft because the only option would be mothballing them if you would like to replace them earlier
To me it looks closer to the real world airlines this way.
Will enhance the AE experience.
If you make millions a day after a start no problem, the money can still be used for buying gates, new planes and so on triggering growth. The thing is that with above mentioned method you have to carefully rethink yr start as you dont get the 5 gates 2 aircraft and 5 million cash anymore.
Sarcasme is geen punt hoor.
