If Square had kept the fast-paced, action-oriented feeling of the few opening hours throughout, this would have been at least a fun, quick romp through a weird story. But dragging the game out with endless fetch quests and terrible combat makes getting to the end more of a chore than anything. In-game achievements and plenty of sidequests give you something to work towards, even when you're wandering around lost.
But without any worthwhile rewards, even they feel unnecessary. If you're looking for some pretty Final Fantasy fan service, replete with Cactaurs, Moogles, and flying Nus, then you'll be able to appreciate the game's great art and creature designs. But Square still has a lot to learn about making a Final Fantasy game that's not an RPG.
