I've gotten Erics Ultimate Solitaire working in Ubuntu, here is how to get it going. It was much easier to get EUS working than SimCity 3000, unfortunately it isn't really pretty since it's dependent on older Gnome libs.
Download eus-lib.tar [ HERE ]
tar -xvf eus-lib.tar
sudo mv libstdc++-libc6.1-1.so.2 /usr/lib
Insert the EUS installation CD
sudo bash /media/cdrom/setup.sh
sudo cp /media/cdrom/bin/x86/EricsSolitaire.dynamic /usr/local/games/EUS/EricsSolitaire.dynamic
Download the EUS 1.0a patch [ HERE ]
sudo bash eus-1.0a-x86.run
sudo ln -sf /usr/local/games/EUS/EricsSolitaire.dynamic /usr/local/bin/eus
Then you can just run eus, or put an icon in your panel for it manually.
