I'm personally not a big fan of randomised minerals, since I like how you can learn about geology from DF (I've learned more about geology from DF than I have in high school).
I guess if you had it as an init option, then those who want it (like you) can have it, and those who don't want it don't have it.
I agree with sockless 100 percent.That said, it might be that Toady feels it's easier to create procedurally generated minerals instead of
FIXING the current minerals.
By that, I mean the physical properties of many rocks and gems are way off (such as melting points, boiling points, relationships with other rocks and minerals, etc.).
Also, I think the gems could use some tweaking:
- Do we really need 27 different kinds of opal?! (Yes, I counted them.) What's worse is that most of these show up as either white or gray in-game...
- The fact that most stone is either white or gray is understandable, because that's realistic - the way it is on Earth. (Although, this is a fantasy game. And there is something to be said for taking a little creative license by intentionally leaving out some of the less colorful stones for the sake of keeping things interesting.) But what bothers me is that so many of the gems show up as white or various shades of gray. Gems should be attractive and gray... is not.
- Fortification agate is commonly found in many gorgeous colors, including red, orange, light blue, and blue-green (cyan). So why does it appear in-game as yet ANOTHER white gemstone?
- Tsavorite appears BROWN in-game. Yuck! But in real life it is a gorgeous "light to deep green". Why should BROWN gems have a material value of 30 ?
- Shouldn't Pink tourmaline appear pink instead of red?
Further, I think the Material Values could use some tweaking. For instance, it's rather boring that nearly all gems are worth either 2, 10, 20, 30, and so forth. It'd be more realistic if the numbers were not all rounded to the nearest 10th.
Finally, the
Materials By Color chart does not list any
bright green,
teal, or
magenta stones. Also, there's only one
cyan (Microcline), one
blue (Cobaltite), and one
dark blue (Kimberlite) stone. This can make it difficult to color coordinate a fortress with local materials, esp. since the availability of stones is random and varies greatly.
Despite all those flaws I mentioned, I still
much prefer the use of real minerals and gems, instead of random stuff that's made up. For one thing, it is quite possible to memorize some of the in-game properties of stones and gems in the current system. If it's randomly generated every time, doing that would be
impossible. And I am convinced all those flaws I mentioned could be fixed with some TLC and patience, without even having to fabricate some imaginary minerals.
