upss, sorry for anyone want to move to opt follow my order.
Install filebox and enable root acces.
Open xterm
cd /usr/share
mv -r wgames /opt
go to filebox and go to /usr/share
on this create new symlink using filebox ( dunno why use ln -s make broken symlink but suppose to be not, may be im just wrong, just to ensure u make a proper symlink)
choose destination under /opt/wgames.
Happy gaming.
