Work is underway to update X Wing to modern graphics, or at least more modern than the Collectors version, two projects actually, in addition to the Redux project which was finished a while ago but is in spanish. One or both of these projects should hopefully be done and available soon. Both will require players to own the orignal authentic disks.
we do what we can, LucasArts may indeed to one or more of the oldies for Steam, that would be great. Just dont know.
