+Maps in Shredsauce will be easier to make. For Jibbin, we had to use 3DS Max to make the maps for the game. Of course it is a great program, but is a lot more difficult to learn how to use. For Shredsauce, you can just make the maps in google sketchup, and then export to Maya. Or you could do it straight in Maya, Maya being a bit friendlier than 3DS Max.
