Hi,
I just found a nice game while browsing the web:
www.airlinesim.aero
It puts you in charge of managing an airline with over 300 potencial aircraft types and about 4000 destinations worldwide. I have signed up and it is very realistic and makes a lot of fun.
Up to today the game was only available in german, but the first international server "nicosia" was launchend in the morning, so you have good chances of establishing your business until others will appear.
Maybe you like to try it out (first 2 weeks are free) and I see you there?
Best regards,
Douglas Dakota
