Mical's In the Beginning piece focuses on character creation and offers a bit of commentary on the new build, new character options, and the author's roleplaying background. There's also a couple of nifty screenshots including one from the new introduction cinematic that shows a freshly created character flying to the Isle of Dawn.
Berman's A Labor of Love entry gives us the low-down on the En Masse employee guild as well as a few anecdotes from staffers who spent time grouping and questing together in the new build. Scapes goes into a good bit of detail regarding customization sliders and also notes that he spent 54 minutes perfecting his character's look.
