I havent gotten that impression at all, do you mind showing where you think Toady has implied that?
I'm not one-hundred percent sure on this, but I
think it was hinted at in the most recent (as of this reply) DF Talk. He mentioned that it would take more than a dwarf to move a stone big enough to allow a statue to be carved from it. It's a bit of a leap (and it could possibly mean that
all stones would be big enough to carve a statue (as is the case now) and are just treated better), but it
may mean that we get different sized stones depending on sminer kill.
If it goes that way, I see miners leaving stones ranging from: heaps of twenty or so small stones (small enough to make stone crafts but not large enough to make a nest box), to piles of a less number of medium stones (big enough for a rock pot or a chair let's say), all the way up to one big tile-sized boulder (big enough for a statue or a door or a single-piece wall). It may be that we get quality markers instead, such as stone vs *<-*stone*->*, which could effect final value of the object it is used to make. Theres also that damnable re-stacking issue to account for.
This seems labour spammy at first, but remember that we're getting a change to allow dwarves to carry multiple objects in one hauling job, so twenty small stones won't lead too any extra tasks over what's done right now; which won't lead to a large amount of extra lag since most of it comes from the pathing demands that hauling jobs create (I understand that storing them in vectors is a bit ineficient when we get to that size, but a pile of ten small stones could be abstracted to be a single "pile of ten stones" item until split by use). Also, if one tile is creating the same
volume of stone, but in multiple pieces, storage may not change. Put all the small ones in a bin, and let the large ones stay as is.
That was a lot of musing and fantasizing and hand-waving, but could you (Toady) confirm/deny/expand-upon(/contract-upon?) any of what I've said above? You may not do another Future of the Fortress pass before the release, but would you like to expand upon what will happen in later releases? And if or when it does get another visit, what release cycle might it end up in?
