Edition 13 is a game designed to allow its players to take on the role of characters in almost any genre, acting out their adventures according to their whims - and of course those of the dice. The system itself is a hybrid of two different retro-clones of the venerable (and long out of print) Marvel Super-Heroes Role-Playing Game: the Costumed Adventurer Simulation Engine and the 4C System.
The structure of Edition 13 comes from the CASE, while a lot of its terminology is derived from the 4C System. However, while both of these draw their inspiration from a common source, Edition 13 considers itself an offshoot of the 4C System since it is mechanically different from the CASE, however minimally. Hence all the references to the 4C System one will find within Edition13.com.
The above is mostly irrelevant to players, though, since Edition 13 is designed to be a standalone game. One need not track down any other books to play Edition 13, though they can readily research and/or adapt material from other systems for use with it. It is designed to be readily modified by players after all, to better suit their sensibilities, whether they play within an original setting or one produced by others.
