Some people seem to speak too much on other's behalf. Microsoft's Flight Simulator franchise is one of the best selling "flight simulators" out there, and it appeals to a large market. If people were getting so bored of it, they would be releasing the 3rd installment with another expansion pack. Let's not think we know it all here. And editor's reviews aren't right all the time. I've seen many a times where a game gets a bad editor review while actual gamers give it high marks. It's one person's opinion, not the opinion of the mass audience. And even many poorly reviewed games sell well. I guess we'll never know how well the "RC flight sim" will appeal to the mass market, since they aren't marketed for it. And finally, there probably isn't a large number of downloads for flight sims because most people don't even know they exist. Before I got into RC airplanes, I didn't know they existed. The only sim I heard of was Microsoft Flight Simulator, and that's due their marketing. Since I never picked up an RC magazine before, I never knew about them. And, in my opinion, a vast majority of the gaming world hasn't either.
