Quite an impressive list (together with the other posts). And here I thought I was a space nutter (thanks Beyond The Frontier!).

Missing the slug throwers Diaspora: Shattered Armistice and House of the Dying Sun though. The former is an Open Freespace mod in the BSG verse with a great campaign, the latter a rather short but still very nicely done pew pew that shines especially on sound effects (and I guess VR but I didn’t try that). Both do TrackIR though (and I even hacked together an OpenTrack provider for the native Linux version of FSO).
