This was kind of an on and off project for me, but in the last few days I finally started over from scratch and finished this thing:
TIE Fighter - Original Videogame Soundtrack
It’s not 100% complete, as the flight music during the game gets arranged ingame in realtime using the iMuse engine, thus it’s basically impossible to have all this music used. Yet, a great suite of inflight music from the game can be found here: Ode to Tie
