Usually only the one, but if I'm going to run a game I'll bring several sets because there's always someone (possibly more than one) who doesn't have one.
And yes, there's no insulation anywhere here. The walls are mostly concrete (with plaster, etc. over top, natch) and when cold weather hits actively start to radiate cold. (I know, I know, technically they're sucking heat out, but it FEELS radiative!). All the windows are single-glaze and they're not particularly well-sealed either, so drafts are common.
Blue is supposed to be the colour, yes. The verbiage is that "blue is an ancient symbol—dating back to Ancient Rome—representing love, purity, and fidelity". This is, however, absolute poppycock. Blue was a symbol of fidelity, this is true, but to the emperor, not in love. And indeed there is no single colour that symbolizes all three things in Roman times.
White symbolized purity and innocence.
Yellow represented marriage and fidelity.
Red represented violence (Mars), yes, but also passion and love.
Green represented beauty, fertility, and love.
Purple represented passion, but chiefly reserved for the royal classes.
Blue was not related to any kind of love symbolism whatsoever. The Victorians just made stuff up. Again. Like the so-called "medieval" torture devices (like iron maidens, etc.)
Central heating (and insulation) is not common here. And cold weather rarely lasts longer than two weeks. We make do with small space heaters at need and I've got the space heater I'm using under my desk right now, keeping my legs nice and toasty. But the thick wooden desk is insulating quite well from the heat source, sadly.
3D printing in metals of various kinds is pretty common these days.
As the proud (and almost exclusive) user of metal dice¹, however, let me warn you that metal dice have a few problems.
As others have noted, you can really scar the wood of tables. What they didn't note is that they can also, if they land just wrong, break glass. I have a nice coffee table that had a glass overlay about 5mm thick or so. (Note the past tense.) One of my d10s landed JUST WRONG, apparently on a hidden flaw that left a stress point, and that lovely glass overlay broke into three large shards. Replacing that was too expensive for my tastes. The solution was to buy a transparent PU (I think?) cover to the same dimensions—only 1.5mm thick was more than enough—and always unroll that over the replacement glass. But you have to be aware of just how damaging metal dice can be. (Other alternatives include using dice towers, rolling bowls, etc., but the PU cover has an added bonus of letting you put key documents, maps, etc. under it for quick reference without worrying about getting pizza grease on it.
They're heavy. Indeed that's part of their appeal, but if you carry multiple sets it can get a bit unpleasant. Sometimes my purse feels like I'm carrying several sets of knuckle dusters or something.
This is one I haven't heard comments on, but they get very cold in chill environments. Were I playing today (3°C at my desk at the moment) I'd use plastic dice.
You'll disagree with it. You won't refute it. You'll walk away feeling better and convinced that you "won" but in reality you'll have just marked yourself as an "enemy" to be ignored. (The human brain is very adept at compartmentalizing things.)
Actual refutation of a toxic idea whose seed has been planted requires detailed deconstruction and reconstruction. It is time-consuming, it is exhausting, and it is unreliable to boot. (C.f. above that compartmentalizing of things.) There is a reason why governments and centuries come and go but culture remains recognizable over the millennia. Once minds are set, they're ludicrously difficult to unset.
I'm going to guess, however, that you will not take this to heart. Ironically for the same reason that your "refutation" (actually mere disagreement) won't take.
I've only played one deck building game (Star Realms) and there were times when it felt like two people playing solitaire, only to suddenly burst into hard exchanges. It was kind of interesting.
In card games I always like that little spice that's added when discards can be picked up by someone else and used. It adds an element of "should I perhaps continue with this less-than-perfect hand, or should I risk helping someone else build the perfect hand?"
Ideally you'd translate it into an idiom in the target language, yes. "Red booklet" would immediately be translated to "little red book" anyway. Red Note was better, but a little off idiomatically. There's a reason, though, why there are actual marketing professionals who get a lot money for doing translations in branding.
No, it's an accurate translation. It just doesn't mean what people think it means because they don't know what the Chinese call the so-called "Little Red Book" of Mao's quotations.
Weird. Weird how I post about Chinese leadership quite often on Weibo and haven't been canned.
Here's a thought: maybe it's how you go about it that counts?
Criticism of Mao in particular is perfectly cromulent here. The Party itself criticizes Mao, especially for the Cultural Revolution, with some fairly harsh language.
But if you don't know how to do it or when, then ... ah ... yeah, you're going to get people pissed off at you.
Would we not rather they utter their opinions in the open so they can be refuted?
It's far easier to lie than it is to correct a lie. When the Nazis come out into the open they spew a stream of lies in minutes that can take months to refute, leaving the field to the lies to spread and fester.
And that's even assuming you think refutation works at all. (Protip: it works so rarely that you can treat instances where it did as statistical aberration.)
