Adding new Circuits to Room Addition... 2 wires or 2 wires + Ground?

...
....should I add a ground wire that leads back to the service panel?
In my hometown, 2 wire and conduit is "to code", but would a ground
wire make the ground more "robust?"
Also, I talked to the electrical inspector and he informed me that 2-
wire and using conduit for ground is a "dirty ground".
I think the inspector answered your question
