Angband has an option to configure, --with-private-dirs , so that the high scores and save files are written to the player's directories, specifically ~/.angband/Angband/save will hold the save files and ~/.angband/Angband/scores/scores.raw will hold the high scores. The executable is not setgid when built with that option to configure. That option affects all of the front ends: curses, X11, SDL, or SDL2.
