I've got a quick question about the game.

[KentaRawr!]

Now, I used to play FFXI pretty often, but after that I stopped for a while. I've kinda been thinking about getting into it again, but I have a question about the game's story. Each expansion pack, as far as I know, has a final boss and its own story. But if I were to start playing now, will the old areas still be the same, with the same story situations? o_o
