Players currently have to hover their mouse over every piece of environment to see if anything is interactable. This is tedious and leaves a lot of information missed. Why waste so much time implementing dialogue and items that players can interact with; if they are largely ignored or just unnoticed?
There is a hotkey that outlines all NPCs. Why not give the few NPCs that actually have dialogue a different outline? Give items that can be interacted with the same outline.
