Personally would like to see SE get back to quests and missions involving the ancient histories of the world again. This trek into the recent past as well as Abyssea are fun, but there's something abuot archeology and the promise of ancients having much more power than we do that just grasps you with an iron fist.
Really wish SE would make another BC with them... Idc what kind of story it involved (maybe getting their armor/weapons...would be nice after all these years) but I would love to pummel that Galk again lol
