KDE3 games are currently linking against libkdegames.so.1 whereas KDE4 games 
are linking against libkdegames.so.4 so from that point of view there 
shouldn't be a problem. You should be able to have both libraries installed 
in the same place without any clashes.

It would probably take some hacking about with $KDEDIRS (since the KDE3 games 
need to look in, say, /opt/kde3/share... for their settings but their 
$KDEDIRS will be pointing to /usr) but there's no reason I can see that it 
isn't possible.

This problem isn't just applicable to us though, I believe it was the plan for 
KDE4 as a whole to allow a way for KDE3 programs to be run without any 
conflicts. Maybe someone on k-c-d knows something?
