Something else than Dei... Who remembers? - There were no enchants in Beta times. Having no Silk Touch to break ore blocks, ores were among most valuable items, and one piece of any ore was worth few hundred Dei. - There were no cocoa beans growing in jungles before 1.3 update. Who remembers selling or buying 1 cookie for 100 Dei and a stack of brown wool for 500-ish? - How much would glowstone cost if we could mine it from the Nether? And what value would gold have if we could trade it? - Collecting Music discs is kind of sport and gamble, even if you know how to make skeleton kill a creeper, you get random music disc, usually not the last one missing in your collection. Collecting chainmail armor is easier, but if you want super enchanted set, it can take a while. Yet, music discs weren't always obtainable, and crafting chainmail armor from fire? It really was a thing. - Spawn Eggs can be thrown on the ground to spawn a mob or put into an item frame to show off, but they cannot be obtained in vanilla survival. - Potions, fireworks, party time, dont mix cacti with puffers! - Have you ever written a book for someone? Or made a map? Then you know that it takes time, and time is money. - Have you ever colored/renamed a set of leather armor? Have you ever lost the name and color when you took it to mining world? - Some players like to have a horse. Some players like to have more horses. And then..... It takes lot of time and resources to breed fast horse with desired color. And it takes even more time to get over losing it because of a creeper. But diamond horse armor was soo expensive. ...yes, expensive stuff. Is there someone who collects it? Is there someone who gives it to friends as presents? What do you do when the value goes up or down depending on minecraft or server plugin updates? Would you like to have a way to get more rare stuff? What way and what stuff would it be?
