Obviously, Alexander is a reference to past games in and of himself, but there's no denying that the Crystal Tower and its surrounding storyline were inspired *specifically* by Final Fantasy III. Considering how successful -- not to mention AMAZING -- it was, I figure we'll be seeing even more such content following suit.

There are an awful lot of hints towards Final Fantasy IV -- which honestly, I've never played (past the short intro sequence, when I was a little kid) -- not to mention, like I said, the new Emperor looks a *LOT* like Golbez. At the same time, though, there have also been a number of additions alluding to Final Fantasy VII, and an Allagan/Garlean "Mako Reactor" could also really hit home. Either way, though, I think we'll be seeing another "Nostalgia-Raid" in Heavensward (and perhaps Hard/EX Crystal Tower).
