Have you tried Rise of Flight?
No, but I've been thinking about it. That, and DCS. I would have to spend some money though on new controllers and such to be able to play a combat sim since the machine in my signature is totally devoted to FSX, and my other machine lacks any of the peripherals I think I would need to play those.
Hopefully, by the end of the summer, there will be some good new airplanes coming out for FSX. If I recall, around this time last year, I felt somewhat similar...lots of exciting planes on the horizon, but nothing presently available, that truly reaches out and grabs me, that I don't already have.
