Better dungeon design?

[civilpaw]

If you played Star Ocean 2 and went to Cave of Trials then you know what good, end-game dungeon design should be like

I played SO2, and did clear that dungeon. And it was fun. But Im not entirely sure it applies to this sorta game.

edit: wait, are we talkin the PS version or the PSP version. Cause I havnt played the PSP version.
