There's also one potential bonus for David, in case he decides on making game editor. He could include user content he finds good enough in official EK versions, so EK could still grow after 1.2 relatively easy, leaving David free to develop new game and in same time, spending much less of his precious time, developing EK's new versions with user created content he officially approves.
In a way it would be a big plus for everyone.
Of course, we will see what will come out of it. I guess that many users who would create content wouldn't mind if it becomes officially included (of course, permissions should be given explicitly, but we could have special thread, or maybe even new forum for user created content, if editor becomes reality).
