tfrost2002: How do I play my games offline? Years ago there was an app for downloading my games for offline play. I have no interest in playing on line as a result I keep buying games and never playing them because I do not want to play online. So why not make it easier for me to download the games I have paid for to offline?
Aside from Galaxy, which can also download Offline Installers via the Extras section, there are a few 3rd party programs which use the GOG SDK.
Three of the downloaders work in Linux, the first two of those also on Windows.
gogcli.exe
gogrepo.py
lgogdownloader
All are command-line usage, though I have created GUIs for the two Windows downloaders, which means no scripting required and usage is via mouse clicks etc.
GOGcli GUI
GOGRepo GUI
So they get close to what the old GOG Downloader used to do, in fact they offer more features, including more control over queuing. However, they don't support modifying download speed or resume. Aside from that they work well enough, certainly if you have a good connection to GOG servers.
By preference I always use GOGcli GUI now with gogcli.exe, as I don't like bloated Galaxy at all.
