eh who would make those freespace campaigns?
PC-users does not have any interest in Freespace 1
(it has almost totally been replaced with freespace 2)
especially now that freespace 2 is open-source.
Linux user's is awaiting the new FreeSpace 2 that will be SDL based
most likely (will also use DX8).
