As of 2.10.3, only two scripts use globbing for DATA_DIRS:
play.it-2/games/play-heroes-chronicles.sh
play.it-2/games/play-war-for-the-overworld.sh
With 2.10.3, the launchers for these games create directories in $XDG_DATA_HOME/games/$game_id
treating *
as a litteral character.
With this patch, the *
are interpreted as shell globbing, so directories are created using the expected names.
