TL;DR: Please (find a way to) place game save files into a conventional directory like
I noticed that the save-games are saved to the installation directory of Stonehearth. This is slightly problematic, as program installation folders are not supposed to get included in backups, and deinstallation should ideally be as easy as deleting the directory.
On Windows, apparently the de-facto standard for save-games is using the user’s MyDocuments directory, putting savegames into
MyDocuments\My Games\NameOfTheGame\ or a subdirectory thereof. Or at least, this is the only directory on my system containing data from dozens of games. The name
My Games is (thankfully) locale-agnostic, i.e. the English name is used on my German system. I can’t comment on Linux, should this be relevant.
Word of warning: Windows 7 and later allows relocating the documents-folder, and the naming convention depends on the version of Windows. Hence sadly this idea is probably harder to implement than it sounds at first. There is no environment variable pointing to the directory.
Another de-facto standard, albeit a bad one, is using %APPDATA% or %LOCALAPPDATA%. While these are slightly better than the game directory, backups are a mess (requiring extensive exclude-rules for cache files etc).
