Sins is nothing like the Homeworld series.... Ok, maybe a little bit, but still

There were some great 3d maps i played in HW, but like was said the most popular maps were played in 2d. While most players played HW in 2d, the 3d option was there to exploit if you wanted to. I think thats what this is all about. The option to use it.
I can see how the 3d maps would get confusing especially if you added in the phase lanes. I played SoTS. I didn't like the game overall, but it had its moments. The 3d map was the most annoying part of it IMO (next to the childish cartoony feel of the game). True being turn based you had time to look over the map. The problem was the map was a disorganized mess of lines. That is just my opinion of SoTS. Im sure anime fans will enjoy SoTS
I can live with the Sins maps the way they are now IF the option of utilizing 3d is there. Be it incorporated in game, or through modding. If 3D maps can be modded in, the best way to avoid the SoTS confusion i guess is to make the maps fully connected (like what also was originally planned for sins), and get rid of the lines altogether. This is all a moot point right now because we cant do that until the game is released. I am just glad to know the option is there.
