That is just another part of the isometric illusion. Turn on the grid (in the menus somewhere) and you will see the tiles better.Originally Posted by xGTx
Starcraft is an amazing example of how through ingenious artwork and some design rules you can fool almost everyone into thinking you have an isometric RTS when it's just using 32x32 square tiles with no overlapping terrain. Diablo II used the same approach. Notice how you can walk up and down stairs, but really you are walking straight and level? The graphics make you think you are going up and down, but really you are staying on the one plane for the entire game. Smart buggers at Blizzard.
