(Sorry for the inconvenience)
GNOME2 is a popular desktop environment that provides many built-in utilities.
NOTE: As of this writing, GNOME3 has not been ported to FreeBSD. Once it has, it may become a desktop selection in the PC-BSD installer.
Note: the Gnibbels and Lights Off games require 3D acceleration. If your video driver does not support this, these games will not work.
