Well, at this point it'd be pressed dual layer blu rays though, i downloaded the entire version and just the amd64 directories are around 45GB in size. I do not understand why they feel the need to associate OS versions with 3rd party packages though, why have an OpenBSD 6.5 version of -say- the 0ad game instead of an OpenBSD version of it that you say it needs at least OpenBSD 6.5 (or whatever) version to run?

(same question about Linux distros in general, FWIW... i just do not see the point of packaging so much stuff for a single OS version, it is like if Windows did the same thing - ignoring licensing - Windows 10 would include Photoshop, Steam, DOOM, Visual Studio, Maya, 3ds max and pretty much every other program with a bit of popularity ever made)

Well, at least a single arch version still fits on a single disk medium, last time i checked Debian needed several DL BDs (although perhaps a single BDXL disk, once they become available, will work... assuming we also ever burners for those).
