He's been running original D&D for a long while in a campaign. In fact, there was a thread on here attempting to incite panic and hatred of 4E (Gee. What a surprise.) over the fact that Mearls was running that campaign as it clearly indicated he didn't understand modern game design, i.e. 3.x/Pathfinder, and couldn't be trusted.That article is such a piece of crap, that I don't take anything it says seriously. I believe Mearls discussed playing 1st edition on the D&D podcast last month. It was a lunchtime game, not "his current campaign."
No. I am not kidding.
