Lol, a twenty year old Toyota will get you to the grocery store as well, and more economically, as a new Porsche. Yes MSFS is beautiful, but compare the system requirements, not to mention the requirement of a constant high speed internet connection, and the aggravation of constant "upgrades" (which seem to cause as many problems as they cure, and are not optional). And from what I've seen, there is no need to learn navigation or systems, MSFS takes you by the hand and points out everything for you.
But there is room for everyone, I enjoy FS2004 as much as you enjoy MSFS, we both win.
