I don't fly realy much, about 7 hours a week.
Bying a used one is good option, convincing my parents is indeed a bit difficult, but my birthday isn't far away so...
I'm using windows 7 now too, but the CFS3 isn't installed yet, need a videocart (can take it off the old pc).
I played CFS3 for about 3 years now, but never been searching for extra's to download, so I only played the basic game. When it runs on win 7 I am going to download a lot.
If your interested the WWII, I can't immagine why you don't like this game.
I'm not specially interessted in the air warr, but I am interested in the war and in plane what can only give one solution.
