There are definitely different locations they have shown off in trailers and etc. However, Atlus has only shown the desert in gameplay vids because it's early game stuff.the writer makes note with p5r they were a new comer to the series , i could see for folks new to persona keeping track of various aspects of the daily events and other factors being easier with pen and paper .
Anyways , read the nintendo wire preview , they bring up that the sandy apocalypse setting could get a bit drab or boring , i do wonder if they change things up later in in the game especially with it being open? otherwise it sounds like what smt has been with the improvements and changes you would expect .
You see lots of trees with a river.
