Wizards of the Coast has posted the answers to the D&D developer’s test I mentioned earlier. Best of all, the answers are those that recent-hire Mike Mearls gave when he took the test, and they feature comments from Jesse Decker, who explains how well Mike did.
I’m not surprised Mike did so well. He’s one of the best designers to emerge from the d20 movement, and I’m sure he’ll do great things at Wizards.
