Many physical games (TTRPGs and similar) will have multiple files available for download after purchase. Sometimes, the number of those files is quite big, with, say, a core book, a supplement, a set of basic character sheets, a set of expansion character sheets - and maybe 3 versions of each of those in different formats, or different layouts for different kinds of printing etc.
I honestly don't understand why this hasn't been added yet with this website existing for how long it has, but could a "download all files" function be added soon, please?
