I am planning on making a freeroam 3D MMORPG where the players run the world and the main goal is survival. How in depth should the story behind the in game world be?

It's your game idea.  How would we know the answer to that?

I worded that really poorly. I was trying to ask how much the story should be geared to help players understand the unique aspects of the gameplay. The game, "Don'know" Is run completely by Players so there is no assistance from NPCs is there any way to determine how much help the players may need?

The only thing I can tell you about story is that for every 30 seconds of story you want to show you need 2 minutes of game play before it. The opening is the only exception but some players don't even like that.
