I would say just add the Xplane board to the top, we would then have a spot for the 4 Major, widely used Flight sims.
As for the combat sims, I think it's fine, we cover the major Heavy hitters, Maybe add a Misc. CS section to cover any we missed.
In the past few weeks, SimV has come a long way in opening it's arms to the rest of the Flight sim world, I can't wait to see where we wind up in the future because of this.

Thanks Pete! 8-)
