What is considered "milking" a franchise?

I'm surprised no one has mentioned Final Fantasy.

If Final Fantasy 13, 13-2, and Lightning Returns. Final Fantasy 7 Advent Children, Crisis Core, and Dirge of Cerberus. Tactics being rereleased on the iPhone and Android. Final Fantasy 3 DS being rereleased on iPhone, Android, and PSP. Final Fantasy 4 DS, Complete Collection, iPhone, and Android. Dimensions, this new card game type one, etc, etc, etc.

Then Mario, Assassin's Creed, Call of Duty, Havest Moon/Rune Factory, Hyperdimension Neptunia, Atelier series, Resident Evil, Street Fighter, BlazBlue, are other heavily milked series this gen.Every time you turn around there's either a new game or a port to another console.

But that's more like I explained back with Dead Rising.

Final Fantasy, as a saga, is not milked. Every numbered final fantasy has always been different and, while keeping the core mechanics (even if XIII did not that, but well), they add things or quit things. However, several games from the saga are milked, such as XIII or VII. That's the difference. I don't consider Final Fantasy a milked franchise, but rather, some of its games.
