Timboli: The installer creator that GOG uses,
Inno Setup, has a maximum size of 2 GB, which was expanded for GOG to 4 GB.
Honestly if there was an easier way to auto-download files, smaller files like 100Mb to 512Mb would probably be better, as you could then pack more in extra space left in spots like DVD's. On top of that, MD5 checksums are fast and easy, and finding a much smaller file to replace would be easier than a larger one. And some people who might still want to write using CD-R's could.
Timboli: And who knows what future technology will bring to the table.
I'd like them to use Blueray packing, but allow it to use Vinyl Record sized writable. Heh be even funnier if you could actually put music on the Vinyl front so you could have it on display or obfuscate it's a backup medium.
Darvond: The more GOG distances itself from paid proprietary software, the more freedom they can retain.
And i'd prefer the closer it is to a straight flat directory extract archive; Then allow running optional scripts dependencies or registry entries, and poof, ready to go.
A man can dream right?
