While I was poking around the web looking for info about Shogo, I stumbled across the Shogo section of the Monolith site. Amongst other things, the ftp site has the full soundtrack available as mp3 (not the incomplete set that GOG has right now), playable demos, patches, the manual and the full source code for the Shogo client and server (the latter being the game code NOT the engine code). It looks like there might be some maps and such there as well.
It would be nice for stuff like this to be part of the downloadable 'value-add' material on GOG if not already present. The more complete the "official" supporting material, the better.
