Theoclymenus: Thanks for the reply and for the information, but precisely WHY do the manual and the game itself get split up in the first place ? You can give me a lesson in the way capitalism works if you like, but I wouldn't bother. It's just ****ing annoying from my point of view, as a mere gamer, that I can't get both the game AND the manual in one purchase ? Am I being unreasonable or are the various parties involved just being a set of selfish ****s
I think the reason it happens is that once a game is finished and out there, development teams get re-tasked to work on new games etc. and the products often go into maintenance mode, and eventually into stasis. By stasis I mean the game may (or may not) still be sold out there but there are no longer developers working on it and it is effectively sold as-is. This is basically the case with the overwhelming majority of games that are still currently being sold today, as they don't usually get further patches/updates/support from the publisher/devs beyond a month/months/year or few years at best for the majority of games.
As the game ages, and they no longer have people actively supporting and maintaining or even caring about it any more, they may not keep the game's code, assets and other materials in a well organized state. Some of it might get chucked into boxes and thrown in a basement file cabinet or similar over time and forgotten.
Additionally, many game titles are sold from one company to another, or an entire company gets acquired or merged and things get moved around. Just think about how we all have crap in our basements we haven't touched in 10 years. Some of it we know is there somewhere and some of it we've forgotten even exists. Only with a company they own zillions of things and employees come and go all the time. The person who even knows where something is stored in the 4th file cabinet in the 8th room in the basement may no longer even work there, and there is generally no financial incentive for a company to go and dig through all that stuff and organize it.
That's the longer story, but the short version is that things just don't stay organized endlessly and they get lost and forgotten over time. Even the original source code for many older games has been lost by the company that originally wrote it in many cases. They just don't have the code anymore, and in many cases they don't have the manuals either.
So now these games are brought back from the dead by enthusiastic companies like GOG begging at a copyright owner's doorstep. They go dig up what they can find and say "here, go nuts" and GOG gets what they get. So, we end up with games that have no manuals sometimes, much the same way as I have no idea where my 3/4" socket is but I think it might be somewhere in the basement unless I left it in a box at my previous apartment...
...you get the idea... :)
Yes, it sucks that video games are not well preserved by the people who created them, but they're as human and disorganized as the rest of us, and in many cases they don't even exist any more, with a game passing from one company to another to another to another over time with each company doing it's best to lose more code, manuals, information, etc. :)
Sadly, in today's digital age where copyright law is taking over the world one freedom at a time, despite the fact that we have the most amazing technology ever in history to be able to archive and store art, data, etc. essentially forever - copyright laws work to thwart that by making it illegal to preserve things for the historical record or other purposes for the most part.
As much as it sucks, it is just a fact we all have to live with. What we can do, is try to track down the missing pieces ourselves via google, ebay, etc. and pass it on to GOG or the company that owns the rights and get them to make it available for everyone.
