Feel free to wish for an entirely different standard, but I'm curious as to where this "expectation" about the "proper" contents of a GOG release comes from. The explicit goal of GOG as a service has always been to make the regular un-modded plain old version of the game in question running on modern operating systems - nothing more, nothing less. While a lot of user-created stuff do work with many of GOG's releases, our beloved Polish pranksters are not in the business of adding entirely unofficial and unsupported mod content to the products (and whether it significantly adds or detracts from the game experience is neither here nor there in this regard, especially from a legal standpoint).
It comes from this quote from GOG... "Thanks to our handsome programming team, the classics are now Windows Vista and Windows XP compatible. Now you can use your lightning-fast PC to unleash the full potential of those games you just couldn't play properly on that busted old 386."
DDFIx does just that. It makes the game work on lightning fast PCs. without that, you have a game that can't use modern screen resolutions. "modern as in... several years have passed since square monitor resolutions has any value to a PC game. I'm not saying its GoG's responsibility to add functionality... but you and I certainly don't agree on whether they should ignore current tech that already exists to make it happen.
The legal comment is a bit much. The results from DDFix could be accomplished with the in house programmers of GoG.
Thief fans have been rigging their game for over a decade. Its sad that an advertised "Modern" installer is out and it doesn't take into account all the breakthroughs folks have made to make this thing work.
I see your point, and I referenced it in my original comment. I think you are assuming I'm asking for opinionated things like texture updates and reworked architecture... NO, I expect movies to play and my "lightning fast" PC to be able to show in an acceptable resolution. Nothing more.
So please tell me... how would adding content that makes the game playable purely from a support perspective to the extra downloads be a bad thing? How is that wishing for an entirely different standard?
When GOG licenses the game for release, which they have to do, they probably can't do much to the game besides the minimal required for the original experience to load and run on modern hardware in it's original form and as well removing DRM. As well, there are those out there that probably would NOT want the original experience tarnished in any way. To them, they can just download it and run it as delivered. One thing that is never going to be won is thinking GoG is ever going to put a bunch of community patches into a game you download. The one exception might be Gothic 3 enhanced edition and that was the developers themselves not distros. All the BioWare infinity engine games are a good example.
We should just be glad that we are able to obtain a fairly priced official license for the CONTENT of the game that we can freely mod using tools and patches provided by the awesome community. That's really what this is about for some of these games.
Of course there's plenty of games on GoG that don't require mods or tweaks at all to still provide a stellar experience.
