well now your actually making a decent case of how rubble adds to the game in a way greater than building walls, one only needs so many walls.
concrete could have a plethora of applications, while rubble walls... you wont need too many.
yes rubble is something to add time to mining, but i fear it will become too tedious as time goes on, or become completely ignored as everyone simply dumps there rubble in a nice big pile.
but now your contradicting the goal of cutting down on items.
the main issue i see, is the rubble idea seems slated towards current game state, not game state one or two years from now. all those systems NW said adding rubble would make harder are getting somewhat significant overhauls in the coming years, and for now if the game is too easy, tough, Toady is working on it.
NW i think you are too set in your desire for this feature, you see an argument and immediately think, "how can I say this is wrong", instead of "well how is this a good idea". in other words, your becoming a U.S. senator
but for now, I think we should simply leave this one up to Toady for if and how it should be implemented, we have discussed it to death across multiple threads and this thread itself, and none of the positive arguments from either side are actually strong enough to persuade me one way or the other. im rather ambivalent about if rubble should be added, but i feel compelled to say no at least for the time being.
