I'm only a few chapters into this story, but I thought I'd recommend it already.
The premise is pretty standard for the genre, with someone going into a full immersion virtual reality setup to play a game. There are some twists to it, as this guy is playing one of the monsters and not the "hero".
It's extremely well written, for the genre, and so far delightful.
One big advantage is that the entire story is complete and posted.

Here is the blurb:

Marty had a fairly easy life as a cook for Arctic Storm Entertainment headquarters when he gets an offer from the company to try out a new playstyle for their biggest VRMMORPG, Oblivion Online. Follow him as he makes his way through the game as one of the monster races trying to survive against the forces of light.


Enjoy!
All the best
