Mori_Yuki: GOG seems to be working hard lately to improve the website and customer experience, so maybe someday soon we will finally receive this often wished for feature
neumi5694: We had that feature once, before they scrapped the GOG downloader. The website offered a link to download all files at once using that tool. It was small, easy to use, elegant. And it's gone.
The new way is to download offline installers through Galaxy or the very popular gogrepo, but that one requires basic skills when it comes to command lines or batch/bash files.
Yes, the downloader, it did its job without bells or whistles. It's no surprise GOG shut it down, not maintaining a piece of software for 6 years, security concerns or simply because other more important tasks to work on. It's no news that some prefer using the website over a client in spite of being an inconvenient process.
neumi5694: Gog simply
can not make a "download all" button without any software on the endpoint supporting multiple downloads. The website can not have such a button, since there is no standard for it (as far as I am aware. Does html 5 support a link to download multiple files?)
It is possible and not necessarily very complicated. There is the <a> download attribute which can be used to implement this functionality and should work across all of the major browsers to achieve it. There are demos showing how a mutli-download button could look like along with source code examples.
On the other hand GOG could also offer a browser plug-in allowing batch downloads, setting up a folder/file structure template and automatic update checks as an alternative to the superb work community members have offered.
Be blessed, ye all and thanks for the work you've invested.
