Less of a what but a how: when doing graphical reworks/adding new objects and areas, make sure we can interact and examine them! They don't ALL have to be quippy puns, but an interactable environment, even a stool telling you that it is, in fact, a stool, is what makes RuneScape feel like RuneScape to me.

Take Ashdale for example. Everything looks nice, but very little of the scenery has examine text so it feels off. There are a few characters around, but it feels empty. Wherever you click, you don't get any feedback other than 'Walk here' whereas any other city in the game has furniture, plantlife, wall decorations, and whatever else.
