The most essential part there is an addition of BoardGame;
subcategory according to
http://standards.freedesktop.org/menu-spec/latest/apa.html

in my case it fixes placement of sirius in BoardGames submenu
of Games menu.

the rest of patch is due to the warnings issued by
desktop-file-validate utility.

$ desktop-file-validate sirius.desktop
