Looking at the new "Meigs" Server, that after the USA, Germany has the second highes number of Airlines. Of course a lot of players are like the team "Deutschländers" but as playing Airlinesim is an investment of both money and time, I wonder how many people are actually succesful with their concept.
Many of those people are going to restart sooner or later. But mind you, operations within the EU are virtually unrestricted, so there’s room for lots of airlines.
No 1 thing I would consider would be the airport location, then the market, both domestic and international markets.
But I like this one (Just spin my globe, close my eyes and put a finger on it… ) and I am going to try when meigs comes back.
