It was pretty cool, except that I wasn't able to finish it. When I got to the combat section, I couldn't find the rat he wanted me to kill. Eventually I gave up and kept jumping off that big ledge until I killed myself, which sent me to the DR, from which I entered the real world.
That makes me wonder, could you also bypass it with /die? That would be handy, for people who already know everything and don't want to go through that whole tutorial again. On the other hand, if they were new and the rat managed to kill them, it wouldn't be good for them to miss the rest of the tutorial.
Anyways, once I got into the real world I realized the NPC server was down. I suppose that's why I couldn't find the rat?
Overall, it did a pretty good job, at least as far as I managed to follow it (didn't get to see the magic part and whatever the last dude does).
