Here is a different poinw about the situation in AWS where is hard to start mid-world and expansion is difficult....
Right now, Im based in an airport where there were 4 airlines (all of them part of respectable alliances and good strategy) and we have cutthroat competition. There are other routes available with unsupplied seats and the survivor of this hub will be ony ONE, the one that can make a profit from those routes when fuel prices will be high. Today.... there are plenty of opportunities, plenty of cash, but not enough aircrafts to execute the strategy. This plane deficiancy in itself, acts as a barrier to entry. And is a part of the game I enjoy.
When planes become less scarce, my fake job as an airline CEO will become an airline scheduling assistant... just schedule routes and that's it.
So I enjoy the lack of planes just like I enjoy the scarcity of slots. Its a no brainer.... you open a route from SAEZ to EGLL (as an example) and you are GUARANTEED to make money forever. You wont get pushed around by competition because there will be no more slots..... So finding this situations (in my opinion) is the fun aspect of this simulation.
I hear "this game is not friendly to newcomers". Well, yes that is true. But that is the whole point. You cant excel at something you are not good at unless you practice. You cant expect to have the same odds of success halfway into a game world than an airline that has been there since the start..... That is not possible. So your objective is to simply start on day 1 and stay there the entire time. If you BK halfway.... then you are out of luck!
