Wow that's a shame too. I used to have them on a different installation of windows one time but never backed up the installers, and thought about checking them out again. The factions one was great, very high res and you could actually add music to it, a wav, aac or mp3 file worked.
I'll do some deep googling, but I'll keep for Factions since we both want that one.

These links still work, so If we find any of them, we've got the music + the ambient background sound for each of them.
I think the part that sucks is that the map and music are still in the GW dat... just no way to get it emulated and run it.
