One of the things I think can be pretty exciting is that we only see military Garlean stuff. Take a moment and picture military establishments, especially quickly built ones, in real life.

There is a strong difference between the features and visuals of a military experience (outpost, buildings, vehicles, gear) than there is with the civilian experience. In this I believe we could be seeing some very visually appealing and advance civilian life styles for the deeply technologically advanced civilizations in our game. With the battleships Garlean's have, like the one that destroyed the silvertear lake, there is no way we don't have cameras in Eorzea except unless SE just wants to because they can (like Fallout games are both advanced and "old" style).
