I have just ordered RoF, as a primary online flyer I have no problems with the required internet connection (since I am always connected anyway). I do wish they would have included more flyables in the original release, the worries over cost of expansions is ENTIRELY in my hands, if I don't want em I don't buy em (the way they did it with the best planes first you will hardly be handy capped by not getting the belerio).
The forty bucks is worth spending if just to show US game producers there is a market for this gendre, since most say no.
