Well i've seen the suggestion somewhere already, but since i ran into
3 game ending bugs (2 i got past with hotfixes, 3rd was a dead-end and i had to restart) i think an editor would not only make for interesting modding (there is -always- people that likes to place little chairs and garbage and other decorating items for hours) but will give the ability to fix these gamebreaking bugs.
Look at Morrowind, it came with an editor..you could edit the game's MAIN file in other words you could via the editor actually edit the game itself. All you did was create a mod that plugs into the main file and voila suddenly there's a whole new area with items which -you- placed. Obviously it can be used to cheat, but it also grants ability to fix those missing quest items, unlock doors, reset some questmobs, place yourself in a more suitable location etc.
Anyway morrowind actually had built in codes to just spawn items and mobs out of nowhere, mainly for the purpose of building mods, but it solved alot of quest breaking bugs without the need for patches.
Either way, imagine the interesting mods you can make out of DD, the fighting is fun (where morrowind failed imho), questing is nicely implemented with
the xp system (so you can actually make a game with no fighting at all and make a pure quest game) and most important of all...IT IS 2D ! Creating a mod
in 3D requires ALOT of work on just "building" resulting in a mod that only looks cool but nothing else, in 2D you can add so much more fine touches and Divine Divinity illustrates how much you can do in 2D very nicely :P Heck not even Baldur's Gate gave me this kind of interactivity.
