There is this difficulty that I wish that was in this game, and that is to discovering technology, and the ability to unlock certain things to be able to use certain good's. It's kinda funny that I start around the year of 100's, and everyone know how to use iron, stones, and whatnot... it's like the know what it is without the need to fully know what is this ore? What can we make out of it? Can we make weapons out of it?
So I am thinking that we need a tech tree, and as the year goes by, the Dwarfs know more about the earth that they are on, and be able to know how to use copper, iron, and know how to use adamantine and smith it into weapons or such. From the beginning of the age, technology is primitive, and you only know how to use wood for basic things, and know how to mine some stones and know how to use ore in it's most basic form. Your settlement need to some short of scientist in the group that be able to identify certain ores and item to know the proper properties so that know what it does, then experiment to see if these items can be used for anything.
I would also like it to see if you be able to experiment on making certain thing's as well, for example... you don't know how to make flood gates yet, but after your dwarf studies the river flow, and combine several pieces of wood... he end up inventing the flood gates, and know learning how to make levers for it to operate... We need something like this in the game to add in difficulty, and more fun into the game, then know everything from the beginning. This make doing mega projects a bit longer, it make the dwarf's actually go out and experiment to invent certain things and gain fame, that might attract more immigrants to a certain city that inventor was born.
What do you guy's think about this idea? should we have some short of a tech-tree which locks most of the advance form of building and usage of certain ore and stone till it's fully analyzed and experimented?
