Hello.
I was just playing PSU, like, just now(I died, got mad, so I came here)
and I was wondering. Do you get some kind of bonus for getting the whole map in dungeons revealed ? Kinda like in Star Ocean ? or am I just wasting my time ? I know it's good to explore and find items, but I find myself going out of the way just to get a vertain portion of the map uncovered.

There is no bonus for uncovering the whole map. Finding every monster and defeating them is how you will get a good bonus (and item reward if you're doing story missions on A rank).
