I just did some math with the gold it costs and will cost in 1.6. Right now, it took 3,072 gold to make that double chest of golden apples. In 1.6 though, it will take 27,648 because the nuggets around the apple change to ingots. If you sell that amount of gold at username/delucacos shop for $17 each you are selling $52,224 worth of gold. With the new amount of gold it takes, you are selling about $470,016 worth of gold. This doesn't give you a 10% increase, but rather a 1100.11% increase. If i did my math wrong then tell me because I'm using an iPad and estimating instead of in-game.
I really feel like GApples will be like books in 1.3. Everyboody bought em and nobody really became rich.
Crafting recipe now requires leather in books. Pre-1.2.5 it didn't so everybody bought/made all the books they can. Now look where they are. slightly more valuable, but the investors weren't made millionaires. Also the GApples will be tough sells since there is so much supply.
