Okay, I've gone back to the actual Q&A video, and I've transcribed what was actually said in re: resources. The video is
here, and the discussion begins at 18:04. They said:
Kate Distler: What I really want to know about, and this is something that I've talked about on my Twitter feed, is I love finding the natural resources on the board and trying to like, you know, set up my cities so I have as much as possible. Are there any new resources in Brave New World? That we can talk about?
Dennis Shirk: There are, but we can't talk about it yet, because it's directly related to one of the other new civs that we're also not talking about yet.
Kate: Well, you heard it here first. There's new resources. It's happening.
Dennis: Oh, sorry, did that not come through? There are, but only as it relates to another specific civilization in the game that we're also not talking about.
Kate: Not a problem. We can talk about things that we're not talking about. So, there will be resources, of some kind.
And that's where it ended. The subject then changed to what Kate was drinking and what was in the box behind Dennis.
Even confirming that the words "linked" and "give away" were not in fact used, I still interpret this to mean that the resource is not going to be something mundane like tea or rubber or chocolate. I mean, to take a previously-mentioned suggestion at random, suppose the new resource is Chocolate. And any civ can get and trade Chocolate, like any other luxury resource, because that's a global product that they would not have any reason to make exclusive to any civ. But suppose there was a new Belgian civ whose UB, in addition to whatever effects the building it replaces has, can take a source of Chocolate and convert it into Fine Chocolate, which provides extra happiness or commerce or whatever. So there is a new resource, and it's directly related to a new civ.
But why, in this case, would he not be able to mention the chocolate?
Remember, the only reason we have any idea at all that the new resource relates to a new civ is that he said it does. Too many of the resources that have popped up in this thread are based on links so tenuous that they absolutely depend on his having said that to allow even the suggestion of a link. If the link between the resource and the civ
isn't blatantly obvious, why would he have said that instead of mentioning the resource
without saying it related to a new civ? Imagine if Kate had asked if there were new resources, and he had said, "Yep, we've added chocolate!" No mention of relating to a civ. Just "We've added chocolate". There would be no logical progression from that to, "They've added Belgium." None of the resources they've included before have had any special connection to a civ, so how would it make any sense for us to hear "chocolate" and start making assumptions about the list of new civs?
I don't think the "question caught him off guard" hypothesis really works. It's true this Q&A did not consist of prepared statements, but the question was just about whether there were any new resources. That's a pretty predictable question. He may not have known for sure it would come up, but he'd have known it could, and he'd be aware of what he could and couldn't say. With a resource like chocolate or rubber or coffee, he'd know he was safe just saying the name of the resource without saying there was any relationship to a civ.
That's why I still think it has to be something where the resource in question is so firmly linked in the popular consciousness with that civ, that he knew he couldn't even say what the resource was. Something like the Murex sea snail, which he'd know would immediately remind a lot of us of the Phoenicians. Or something like buffalo, which
could be added without a new civ, and which was used by more than one group, but which would get most people thinking about the Sioux quickly enough that he would know that even mentioning it would start the speculation. Whether the new resource is actually exclusive to the new civ or not--and that much is not clear--I interpret his wording to mean that the reason he couldn't identify the new resource was because, even if it didn't give away a new civ directly, it would hint at it
so strongly that it just wasn't "safe" to say anything yet.
I could be wrong about that, of course. Maybe it really is something so totally mundane that this whole discussion will make it seem anticlimactic once we find out. Maybe the only reason he said he couldn't tell us was that he knew it would be fun watching us speculate about it. Who knows? But based on what he actually said, I genuinely think that it is
not going to turn out to be anything as general as chocolate, coffee, rubber, tea, rice, or corn, where one
could find links with any number of civs if one were really trying to. I think it's going to be something that, if he had said the resource, it would be as good as giving away the civ by name.
