for two green help entries:
To install Dark Oberon there are two files for Ubuntu on the page you linked to (dark oberon and dark oberon base), both have to be installed, first data and then the smalller one. It also creates an entry in Application-> games
and scorched 3D is in Applications/Add/Remove
I just checked out urban terror and it seems to be free.
You can use quake 3 arena loader to load the game or you can use ioUrbanTerror, if you use the quake one you probably have to pay for it but when you use ioUrbanTerror, then it seems that the game is completely free.... :)
Another game that could be added to the list is Soldier Of Fortune.... http://www.lokigames.com/products/sof/
Maybe a games section could be added to automatix ... or take the automatix code and re jig it to install games instead?
What Id really like to see is klik packages of all the "top" games
"Soldier Of Fortune.... http://www.lokigames.com/products/sof/" --> Domain expired!
"packages of all the "top" games" --> Im on it!...
There is one game missing in this list:
Total Annihilation: Spring
That's Total Annihilation in 3D (some sort of supreme commander in a way ^^) and it's free. :D
Maybe this should be moved to the wiki.... better yet help these guys out http://www.ubuntugames.org/
btw tremulous is in "Add/Remove Applications"
Dark Oberon in the list isn't like World of Warcraft it's an 2d RTS like warcraft2
