I think it was the Saiyan Saga... When piccolo was training Gohan to get ready for whoever was coming (sure it was vegeta and nappa) But it was like a desert area with lots of stone platforms and cliffs etc.
Just think of when Vegeta turned into a monkey thing and Krillin tryed to cut his tail off with a distructo disc and vegeta moved outa the way and the fat guy cut off his tail with his samuri sword. Thats sort of area i think would be great for a map.
but it'd be easy to make a map like that, just a coupla rising stones and stuff and u could say, "uhhh yeah, its uhh based on the uhhh place where goku fights vegeta!"
most places that they fight are in the desert with a coupla cliff things around em: saiya-jin saga as u said, frieza on namek, frieza returning, androids, cell, babidi part, and buu part, infact almost everywhere they fight is in a desert with some rocks and cliffs around
