Do GOG actually pack or re-pack all games?
Flyingfluffypiglet: As the offline installers are Gog packed, I would really like it if a Blue could chip in and enlighten us as to how they go about including, or not, the option of integrity check. Perhaps indeed as you suspect it's only games of a certain size onward that are deemed worthy of that option, or it could be an oversight, or who knows, only Gog does.
It would be nice to know, but there might be a bunch of variables to that answer.
As you say, all games should have an integrity check regardless of size.
Flyingfluffypiglet: TBH, it would kind of bother me if smaller games' integrity was skipped, because you can never guaranty you won't have corruption, or a bad pack, both can and do happen. Okay it was not a game but as an example, a few months ago, there were issues with Witcher's goodies, which had to be repacked, and they were not small files. Fine if you're on a good plan, bad if you're capped.
If a small size though, I guess using my GOGPlus Download Checker program will check fairly quickly, but that of course relies on internal checksums existing to give a true verification. Failing that, you are left with the download checksum verification, which currently requires Galaxy or gogrepo.py.
P.S. I guess it is possible, that the program (i.e. InnoSetup) used by GOG to create the installer, always provides the internal checksums, but they may not always be checked when installing. In that case, my GOGPlus Download Checker program would certainly be worthwhile using. In any case, it would show you on use, what it found.
