Where Can I Get Better Repositories For Games?

I really want to have more games on my computer but the Suse repository doesn't have any good games. I want games as OpenArena, Quake 3, Urban Terror, Enemy Territory, etc... Where can I get games like these? Apparently, people get Sauerbraten and Nexuiz using the default repositories! Why don't I get these games? I use openSUSE 10.3

EDIT: I think I found it... By browsing, I found this: http://download.opensuse.org/repositories/.../openSUSE_10.3/

You can also use a package-search as provided by openSUSE, example: »klick«. Be careful with adding sources, though.
