You don't build books in Civ. Therefore, you can't destroy them. Your "explanation" is not satisfying to me. You are just inventing things as "arguments" in order to "win" some debate.
Nobody's inventing arguments. We are just *trying* to explain to you why we, in our games, don't see a problem in this feature that apparently bothers you. If you choose to discard alternative points of view as "inventing things as arguments in order to win some debate", then you're just limiting your possible enjoyment of the game in this case. You're free to do that, of course.
I don't think you're treating Olleus' explanation fair btw. Sure, you can say that there are no books in the in-game libraries. But Olleus wasn't talking about abstract game features in this sentence, but about historical realism and plausibility. Certainly it's not unconceivable that a building which is called "library"
might contain books, which
might be vulnerable to fire, which in turn
might offer an easy possibility to destroy a library without tearing a whole building down. The game doesn't explicitly specify that its libraries contain books or scrolls, but this is an historically plausible way to look at it.
Now you're saying that using historical plausibility as an argument is just "inventing things to win some debate". However, you yourself were using the very same reasoning some posts above, when you said that you "don't think a couple men with charriots could destroy stone buildings". So what did you do there - inventing things to win some debate? Either using historical realism is an acceptable way of argumenting - then we can assume that important buildings are made of stone, and we can just as well assume that libraries contain books. Or it's *not* an acceptable way of argumenting - then we can not talk about books (because the game has no books), but then we can't assume that buildings are made from stone either (they could be painted cardboard or anything, most of the time you don't even *have* stone as a resource when you build them). But using historical plausibility for one's own arguments, while discarding it in others' arguments as "inventing things" doesn't really work.
Plus do you have a source where you see that a victorious general can't prevent his soldiers to loot? I have one that says the contrary, the nowadays events.
Really, this is common knowledge about classical and medieval warfare. I wouldn't say that it was totally impossible to prevent looting, but it was mostly common practice to allow it - sometimes for a fixed duration, i.e. the soldiers were explicitly allowed to loot, destroy, rape etc. for one day, but on the next day order had to be reinstated. You'd need an enormously good discipline to prevent that, because when a winning army enters a city, you cannot really control what they're doing, you can't even *know* what everyone is doing. You'd have to rely on the victims to vindicate any misoings ... and if you do really choose to punish your troops based on something the "enemy" said, then good luck with your next mission, you'll need it dearly ...
Btw... the fact is that it annoys me and that I fail to see the point here.
Well, this is a forum. If you tell people that something in the game annoys you, be prepared that others voice their opinion. They may agree with you, they may see things differently, they may even offer insights that might help you adapt to a game feature that annoys you. If you see no point in that, then, well, what did you expect? What *would* have a point then?
