I think there are extra factors involved with the king. My Queen took a while to show up, and I think there's a war on with one of the dwarven civilizations. Also, you knew the rules on artifacts. If you feel you wasted your dwarfs' time forbidding stone, I am truly sorry. But there's no way the rules are changing for a late competitor, when everyone else played by the original ones. Some of us created more wealth than you early on, and didn't get half as many moods. I got a megabeast instead. It would be highly unfair to base more of this than can be avoided on luck.
And the reason others aren't being asked to recalculate their wealth to remove artifacts is that they aren't even in the running for the economic competition. I'm not either, anymore. When it comes down to you and Zifnab, you'll have to each remove your artifacts to see who wins. If I'm still up for third, I'll have to do the same. For the others, it's irrelevant so I guess no one saw the need to bug them about it. Notice those who have not given accurate non-artifact counts have a posted (?) beside their stats on the board, as in every other category where their counts are not explicitly explained.
For my personal opinions on dwarf wealth, well...
I believe that you should have the option to mandate a certain quality of product from a dwarf, who then works for the necessary time to create it. No materials wasted by a legendary craftsman, right? Not removing the current "work how you want" option either, it just takes longer to always make a good product. And of course dwarfs could only create within their capability. Also, a Masterpiece work is traditionally what qualifies an artisan to be a "Master", so they should have to work a while and create one in order to move up to Master and gain the ability to be ordered to create high-quality works. But it's not my game, so we will deal with an extremely random system, and until Toady (bless him) has time, a very unbalanced one. Heck, my accidental food megamania would have topped 6mil if my best cook didn't decide to go out and play tag with beak dogs in early year 4. Food is unbalanced, so is admantine.
If you want the same old explanation, here it is:
In short, no amount of complaining will make artifacts a valid form of competition. The rules were clearly stated. You can make a lot out of luck, but you can't force luck to happen. Players who don't get moods or get dwarfs who grab a single silver bar the moment they claim the shop don't get the luxury of dictating what is created. Even if you can influence the type and number of moods with skillful play, you can still beat someone who happens to get 1-2 material moods when you get 3-5 material moods by sheer luck. If you want an artifact competition, host one.
You clearly disagree and you continue to state it. But the rules won't change, and a happy competitive attitude would be better than sulking about it. We all played by the same rules, you're at no disadvantage. If you think basic subtraction will be a problem for you, we can help.
