Quick poll on peoples thoughts about quests in game

Hi I am thinking about how to make my online game different/less boring then other ones and wondering when people do quests do they care about the storyline or not (like do they just skip though read the objectives and get on with it).

I am asking as one of my improvements to the game is Npcs speak as well as the text for example if the text says Hi the sound Hi will play and for quests it would go a long the lines of:

-clicks the quest button to get info-
-NPC quest dialogue shows and the linked sound also plays- eg I need you to kill some rats that have been eating the food stores supplies
-once the player clicks continue that audio stops and the next plays of there responses-

Would people be more interested if the story was told verbally (there will be an option to mute and change volume of music ,sfx and Npcs if you want to hear none,some or all )

sound in NPCs makes the game much more interesting!

If i do manage to find a way of doing it ill need loads people so it sounds better i might also have just few random phases like hi etc for wandering villagers and guards

I would like to see more sound in NPCs. Like swtor, all of the dialog is voice acted…

True. Or you can get a few and have them imitate different voice
