The kdegames package does require its sub-packages, but the sub-packages does 
*not* require the main package. This is called "meta-packaging". Take a look 
at the specfile and you will see.

For example: if you install kdegames with yum, it adds all the sub-packages as 
dependencies. But if you later uninstall kdegames-foo, it wil only uninstall 
kdegames-foo and the kdegames meta-package. All other subpackages will remain 
untouched.

The idea on creating yum groups would satisfy this "problem" and the issue in 
comment #10 at bugzilla. But IMO creating such groups in yum would pollute 
the yum's groups and it's not exactly what we want.
