I mostly agree with Stabbey. It seems like a very delicate thing to bring, as the editor would have to be perfect in its own way first. If either the editor or the DM mode isn't clear, easy, and powerful to use, it will be worthless and will just have wasted money.
Also, it will only benefit parties of 3 or more players, because I don't see the fun in playing a 1v1 dungeon. This seriously reduces the potential playerbase, as my guess would be that, especially after DOS1, most people are either solo players or duo-players.
Anyway it's the very last stretch goal and I don't really expect we will reach it. Which is maybe why it was put in last position...
