Oh well, if you are for quality, why just don't you buy the CDs?

There's every chance that the original soundtracks weren't great quality to begin with from the source material...
Besides, the thing you lose with MP3's is bass and treble response. Re-recording at 320kbs is very unlikely to remedy that. If you want quality, you need the original PCM recording (ie: a CD.)

I think GOG can pretty much only provide what they are provided which most likely aren't the original CDs, so they can only go off the audio files they have.

If nothing else, you get virtual CDs with Earthworm Jim 1&2 which are provided solely for their CD audio. I'm sure there must be a way to rip from those using Daemon Tools or something.
But yes, I think that GOG just provide what they're given by the publisher.

Or the Intertubes ;-)
(Replacementdocs anyone?)

Pretty much every game since Windows 95 has included a digital (usually PDF) manual. They wouldn't have to rely on another site for that. Plus, the publisher would have to agree to its inclusion anyway. Which defeats the purpose of obtaining it from another source.

If you ever find a copy of a Fallout promo soundtrack, feel free to let me know.

I ignore what is the actual quality used by the soundtracks GOG provides, but for all effects and as long as they were using a relatively new MP3 encoder (for example, LAME), 192 Kb/s is practically transparent, i.e. you won't notice the difference between the MP3 and the original (hopefully lossless) source.

Eh, I meant that in one of the games I've purchased there was a manual clearly coming from Replacementdocs. It wasn't a question, mine was an assertion :-P

That's... odd. Which game are we talking about here?

I can confirm at least some games' manuals come from ReplacementDocs. I don't remember which one I saw in my collection, but I'll be sure to let you know when I find out.

Shogo - Mobile Armor Division from Monolith.

Now that really is strange. Not only is Monolith alive and well, but Shogo isn't exactly the oldest part of their back catalogue. How could the manual have been lost? Very strange...

Not at all, simply it's easier to build on the community work to speed up releases. Maybe in the case of Monolith there isn't an explicit permission as like as in the case of Blizzard, for instance, but surely the GOG team asked Monolith about the issue before including the PDF....
