Its a very experimental series. The Legend Series is closer to the NES era FFs where there is no real protagonist and your just a nameless party but then again its a party that can be turned into robots and monsters.

The PSX era Saga games are more story focused but I'm sad to say my experience is little. I kind of missed them for some reason. The Saga Frontier is basically you choosing one of several main characters and finishing there stories, its basically a game with half a dozen smaller games packed in it. Saga Frontier 2 is a generational story letting you see the history of a family. Of all the Saga games, this one seems to have the best reputation. The PS2 one is infamous for being one of the worst games Squenix has ever released.

You know, we never did get any of those DS remakes...
