Good question. The X series are also wonderful in many ways, but more focused than FS/FS2 on the 4X strategy aspects. They have no community modder campaigns vortex like the Freespace community features, along with the accompanying space combat effects that have been so incredibly developed by the FS modders. The two sims are more like cousins than brothers.
Like flight sims, I guess this genre isn't dead but doesn't hold a place in the PC world that it used to.
