newbieT,

What you are not taking into consideration when you mention games such as Doom3, Unreal, etc., is that these are marketed and sold to a much greater percentage of the public than rc flight simulators. So, idSoftware makes their profit from sheer volume of sales, making only a few bucks per sale, whereas, Knife Edge Softwae and Great Planes have to make more money per sale to turn a profit. Certainly, if they sold as many G3's as Doom3's, then the price would probably be comparable.

You are also getting hardware, the controller, with the software. Adds to the cost.

I don't mean to belittle you, just pointing out the reasons why they are charging so much. That said, I do believe they could sell this for $150 and more people would buy it.
