Thanks @ Meer!
Yes, there will be some sort of soft limit but unlike the hard limit now.
I don't really have all the details yet, but setting up hubs will be increasingly harder if you already have hubs
As for having the game real time it would be pretty hard, as most of the simulation is based on the weekly model. That would be a very major rewrite and might lose some realism in the simulation as it literally should take airlines years in order to recover the cost of a plain, so if we do not use a virtual time that passes faster then either the margin would need to be unreasonably high or the players would have to play it for years in order to make even on any investments
