I might just have to check the demo out. I have always wanted a civilian flight sim since Sierra's Pro Pilot.

Just never got around to it.

Anyway, I was checking out the requirements. They seem benign enough, except for how much HD space you need. I have never seen a game require so much space - 14GBs!

I've got a 250GB HD with still about 80% left, but 14GB is still a very large chunk. Here are the entire requirements for those interested:
System Requirements
- Windows XP SP2 / Windows Vista
- Processor: 1.0 Ghz
- RAM: Windows XP SP2 - 256MB, Windows Vista – 512MB
- Hard Drive: 14GB
- Video Card: 32MB DirectX 9 compatible
- Other: DX9 hardware compatibility and audio board with speakers and/or headphones
- Online/Multiplayer Requirements: 56.6 kbps or better for online play
I didn't see them listed at any other site I checked out. Somehow, I even managed to miss them on Microsoft's site.
