Three things that are most annoying:
1. The game crashes every 5 mins back to desktop. I can here some sound and i can hear my plane crashing but thats all, no switching back to menu or something like that. Just the Taskmanager helps.
2. No Radio. I mean you can´t play with AI if you can´t give them orders. If I try to land they to land too...without wheels
3. No AA. Yep this makes the game looking not that good as its supposed to be!
