That's great news.
There is a whole bunch of stuff that *can* be figured out using some of the current editors, figure being the operative word.
Having the real editors will be (to use an american word I use too much Awesome!) oh god, loads of information etc., but we need the details of the numbers
you can only go so far without the database of numbers. Will you be releasing the game data as well as the tools ?
I'm guessing not, as that would allow cloning and re-branded/re-sell by bad people.
but: details of the structure would be good
basically whatever you can, and keep the company safe.
What would be good, and perhaps, maybe, more nice adjs, useful, is a way to hook into quests. if its easier to do a side quest off a parent quest, all the better, more integrated with the game, would make for great re-runs with old characters. Nostalgic go-backs, cool stuff really.
I don't know *anything* about the game engine, but I guess there is a basic quest desc format with dialogue triggers and QuestID stuff, and then completion criteria, pre and post, actionable items (is that a word, spell check says yes) that you can use in cell code. sorry I don't know what you call the referable location elements: i call then cells.
Seeing as you guys are not too busy or anything right now
, a document, yes I mentioned that actual word, would be good
As a developer myself, I would suggest this: leave it for a year after release of III, on the anniversary. We will all still be here.
Then we can all go mad adding new stuff
