Oh and with regard to the "questing is still levelling" comment, I disagree.

To me, grinding is the concept of repeatedly doing the same thing over and over to advance your XP/cash whatever. For me, that's when you're killing orcs at 100xp a pop and you need 5000xp, which translates to 50 orcs at a rate of one every 90 seconds so it'll take... well, you see what I mean.

Questing on the other hand provides a storyline and motive (however thin) and - when done well - becomes the driver to continue playing.

Levelling through questing should be a side-effect of questing and in good games it is.

On many occasions I've found myself shocked when I've seen my character level-up at a quest turn-in, simply as I've been so engrossed in the events of the quest that I'd failed to notice how close to my next level I was.
