I have been playing AEn for the past few months in my scarce spare time. It is a challenging game to master compared o AE. Competition dynamics are much more realistic and difficult to manage. Route scheduling is an absolute nightmare to spend time on. For perspective, scheduling some 777s to fly a 15 hour flight to the us from Muscat took me nearly an hour. Because specific timings of routes and days need to be set up. By comparison, I used to set up routes in AE in well under a minute. It’s a massive difference.
