I really wanted to see housing in game, It is a shame it has taken so long and that we have no real detail about it, or if it will definatly be added or how if it will, or even a good hint would be nice i think.
It would also have a lot of crafting potential with decorative items being added, Growing plants would be fun, as i never got to play FF11 i'm really interested in seeing if it is added here.
