There's some perl games codebases to start writing games in SDL and OpenGL with input and output here :
https://github.com/zork9/repository/tree/master/perl-repository
You can write action, shooter, platform etc. games in perl with it.
There's no code (or any other content) at that address. All it had was the heading "svn-gen - Revision 24761: /perl-repository" and a ".." link (i.e. to the parent directory "http://soft.vub.ac.be/svn-gen/").
