Я тут покопался в торговых системах старых Final Fantasy — никогда не обращал внимания, как это вообще головоломки, которые ждут, когда их решит хитрый переговорщик?

You’ve got the right idea, but remember the early RPGs didn’t just let you flash your wallet and win; each vendor had a subtle pattern. In the original Final Fantasy, for example, the merchant in the merchant village will only drop a certain item if you’ve already purchased a specific number of other items—so the trick is to “set the price” in advance. And in Dragon Quest, the shopkeeper who offers a discounted sword is actually a test of your knowledge of the in‑game calendar; the sword is only sold on the 25th of the month. So yes, you toss coins, but you’re also playing a very long, very patient chess match with the system.
