Without exaggeration I have had to download a zipped tar, that contained a rar split into ~100 parts, which contained an iso which contained a custom installer that extracted the compressed game files.
Seems to be overkill.
With an unpacked release I can pick and choose what to download, if it’s on a newer patch level I can just point it at an existing folder and it will just download the difference. And of course I don’t have to jump through the stupid installation hoops.
