One of the greatest parts of DF is that unlike many other open-ended games, it actually generates a history along the way. But other than new characters, buildings, items and events, I realized it doesn't do much. But wouldn't it be awesome if people could 'invent' objects? Like sciencedwarves who spend their time researching-n-developing new stuff. Kind of like making an artifact except being useful against being just expensive, decorated items. Imagine making, random stuff like, umm, canning machines which can can meat or a new way of making weapons which make them even more powerful. And perhaps not all inventions will be made at the same time, perhaps, some worlds even don't have particular random inventions. I'm already imagining making labs with lot of books and workshops with sciencedwarves researching. And by the time Toady includes alchemy, maybe, even random potions? And after something has been invented, it might become famous (always available) or perhaps your sciencedwarves have to read books to find out about inventions.
Also, perhaps some certain random material are unknown, and once you discover it your sciencedwarves have to test it and figure out what it does, and will give you a list of what it does and will give it a name. Of course, it's only certain stuff, imagine if you had to find out what is siltstone XD? It may have already been discovered or worlds may exist where the substance hasn't yet been discovered.
Ok, and if these are ignored, at least unique spells discovered. Or heck, even unique food recipes which might become famous and be made by dwarves a thousand years later.
Anyways, even if these are taken into consideration, it will be quite long until they are implemented
Of course, it's just my ideas and if they suck, I'm sorry. How do u feel about these? I believe it may make each world even more unique even if only some of the ideas are implemented
