...syncing Vatsim with a headset to Xplane completes the ultra-realism and usefulness of this tool allowing one to "file" and fly an IFR flight while communicating live with "ATC" (experienced real people, real time taking on the role of ATC via the internet)- it doesn't get much closer to reality than this and I have little time for folks that call it a "game"- it's all in how you use it.
