Like many others, I'm thoroughly enjoying my time with MSFS.
Not only is the default topography fantastic, there's also the excellent photographic overlay to go along with it (how much would that cost in the past?). Then there's the added challenge of sloped runways (like X-Plane and more recently, P3D), plus some wonderful weather effects.
Yes, it's not complete (or finished some would say), but then again, I can't remember a sim which has been. If you're looking for the perfect "binary" flying experience, then all previous simulators have been incomplete in one way or the other.
I'm just grateful that we have a range of simulators to choose from. None of them are perfect, none of them are real, but all of them in their own way are enjoyable.
