there are endless possibilities to improve it even more. such as more airports(come on... no Frankfurt int Airport, nor class 3 Berlin?) or planes. (at least 3 new ones by now).
All in all nothing has changed since 2012 when I started playing it. Doesnt change that it is an extremely addictive game for which Id even pay as a standalone game!... come one, ingame purchases suck- but for long time players the lack of updates is not motivating.
