Initiated by member of the merged Debian/Ubuntu-Games-Team and Hans de Goede from Fedora a mailinglist[1] was created to draft inter-distro collaboration for maintaining Games[2]. The aim is to share and review patches as a lots of games need lots of patches or are even upstream-dead.

While still an new idea, at least FreeBSD and OpenSuSE already joined this effort by Debian and Fedora people and KDE-Games as an upstream seems interested as well[3].
