darktjm: I used to just use the web for offline downloads, and now I use lgogdownloader. Never used wine for the download, and if I did need that, I would've avoided gog.
As to the installer, there are some people here who write installer scripts that use innoextract so you don't have to use wine to install the game, either. I don't see that as a big deal, though. The only time it sort of annoys me is with scummvm and dosbox games, since they do package other scummvm and dosbox games with Linux-native versions.
Yes, both are user-supplied solutions rather than gog-supplied solutions, but the only thing you need wine for is to actually play the game (and in some cases, there are actually 3rd party Linux-native binaries you can obtain, such as for Jagged Alliance 2 and Oriental Empires.
I'm curious about using the web to download offline installers. I don't know much about GOG, but it seemed to me it's not possible just to download files - it's just possible with gog downloader? Which is a windows executable.
I just had the worst experience with installing Witcher 3. I think it beats out any triple DRM game installed through Steam+Uplay/Origin+Denuvo/other random DRM. This was already a readymade and tested script from Lutris, by the way, and it used the offline installers. The installation itself took ages (after the download) - I'm talking about 45 minutes to an hour or so on a good rig. I thought DRM-free meant less hassle...
Thanks for letting me know about the 3rd party tools - it's the first time I've heard about them. The gogdownloader for linux is essential to start with.
But actually, my preferred future method for installing games on GOG will be to WINE/Lutris GOG Galaxy, and then let it install and update the games through there. WINE'ing the manual update was almost the last straw ;)
Sorry for the rant - it's just been a while since I had such an experience getting a modern game to run, even on linux. I don't actually mind too much to fiddle with things to get stuff running - I'm just worried about my recent decision to renounce Steam and move onto GOG thinking it would be a smooth transition...
