Interactivity
Something I'd like to see about interactivity is that NPCs talk about it more, or about items and mundane, but real things, in general. I mean, we can do all sort of things in the world, move all sorts of objects -- but I'm wondering if it's "just there" or if it actually has meaning for the NPCs in relation to the player characters.
Simple things, like "Could you fetch me that stool? I'm feeling dizzy." And you do, because you can. Or a master smith telling his prentice about various weapon types, or guards practicing with them on different types of targets.
Usually RPGs are very pragmatic in that regard. You got your quests, NPCs that talk about quests, locked doors that need to be opened and enemies to be killed. Most of it is story or combat related, the artwork and items themselves are only "there" (since there is no interactivity anyway).
