How much are emeralds worth compared to slides (and vice versa)?
And what about the emerald / slide blocks?
How should one state the value of something?
I don't know how to convert slide blocks or anything into real money, or any made up currency in your minecraft world.
That also depends on the seed of the minecraft world. Nevertheless, emeralds are rarer and therefore more valuable.
I mean if I give someone 18 Emeralds, how many slides can I ask for exchange?
You can't say that. All you can say is that emeralds are not worth it because you can get them cheaply from Villiger
Emeralds are actually worthless, even if the ore is rare. With a villager you have infinite benefits.
No idea depends on how many diamonds and emeralds there are in the world.
