If I was still into top down games I bet we would see all kinds of sounds. The ones from Zelda:OOT was probably the most biblical. Especially for young link leaning over just to get the item, and almost fall into the chest.
Two of my favorite games, has a simular sound let me go check, since I have all three games at my disposal.
