Hi, as of today Stunt Rally is not included in the official Fedora repositories (nor in the RPM Fusion repo, as far as pkgs.org can tell me).
After a quick search I found an ongoing effort to package Stunt Rally for Fedora, see:
http://copr-fe.cloud.fedoraproject.org/ ... tuntrally/@CryHam: This might be of interest for you, this packager wants to remove some of the bundled libs to make the packaging cleaner and rely on system-wide libs. Maybe you could give him a hand? See:
