This has been suggested before here.
It’s just very hard to sell worlds, usually you just waste all of your gems on global messages before finding a buyer.
It would be helpful if we could put worlds for sale on PWE, so more people could see one’s offer without that person spending lots of time and gems on advertising.
Unlikely and unrealistic, what happened if ppl drop items or take items out of the world when selling in the PWE? How can ppl be sure of what they are buying?
By items, you mean items in chest?
People can’t see the amount of them when trading the regular way neither.
If you mean blocks and dropped items, there is a very simple solution - they could make it impossible for the owner to alter the world while it’s on sale.
You wouldn’t just randomly take stuff away from the world after agreeing on the price with a buyer, right?
So that solution wouldn’t be a problem.
