Outside of the wallpaper, virtually none of the areas in this game are interesting from a layout perspective because they are all nearly identical.

But my personal favourite is Gran Pulse, if only because I can go back and forth and explore to my heart's content. Still, GP is disappointing because it's such an anomaly in the rest of the package that I can't help but wish SE integrated it better into the rest of the game world. Also, it's really not all that well developed either. It really only exists for the single sidequest, and even the sidequest itself seems tacked on being just billboards of vague backstory leading to palette-swap enemies who drop mildly useful items or activate more datalog entries. None of it is as compelling as it could be.

Least favourite - probably chapter 10's obstacle course. Completely killed my interest in the game for at least three weeks. Taejin's Tower is also an obnoxious waste of time.
