Just have an idea want to share,
I believe a lot of players really don’t like running around to find the items on current econ system.
This why a lot of mall come out, but still its a nightmare to find the items you need.
My suggestion is a marketing UI machine design like a monitor, so it can also be part of the decoration in the house as well. A market UI machine allow players to list and find the items. Players who are listing the items can also write down the shop name as well. So players only need to promote their shop with big sign or blocks design in every active city.
The current situation is like we can write the sell list with sign for sure, but usually its small and hard to get people’s attention. Or players more rely on discord or forums to promote their shop. With the market ui machine, players can list the items on the UI, and promote the shop with Sign. I believe it can change the shopping experience to next generation.
Also devs can improve the global chat channel with less condition for players to use. This will allow players to ask question and shops location easier, and make the game looks more active for new players.
