On Linux, the XDG Base Directory Specification[1] defines the paths inside the user's home directory that should be used for different purposes. Barony currently saves the data files in $HOME/.barony which ends up cluttering the home directory even more than it already is or needs to be.

Ideally, cache should be in $XDG_CACHE_HOME ($HOME/.cache), data in $XDG_DATA_HOME ($HOME/.local/share) and configs in $XDG_CONFIG_HOME ($HOME/.config), but everyone dumps everything either in .config (Undertale, Unity, Hyper Light Drifter, Vintage Story) or .loca/share (Godot, Steam, Mindustry, FTL) anyway.
