I don't wanted to say 3dgs could come without WED and MED. And WED is not overall totally useless, but my opinion is, that get to less for too much work in WED (sorry for the bad english, hope you know what I mean

) Maybe Hammer-Editor is a little more complicated to learn, but if you get to know it a little longer you will find out, that its much more powerfull than WED. I prefer building the objects in other editors and put everything together in WED. This works fine.
