Just a polite request not to use acronyms for module names, there are so many that I find about half the time I have to stop and research to figure out what people are talking about when they only use acronyms for the titles.
Earlier last year, I began working on revising Reavers of Harkenwold in order to revitalize a return to 4th Edition using only Essentials as an OSR-style game. I will be returning to that as soon as I get settled into our new home in Washington.
I am about a quarter at most through running Princes of the Apocalypse in my one group. My other group is about to start Shadow of the Dragon Queen. The former group is normally just official adventures, and the latter mostly just my own, but every few years I do run something official for that group - the last time was Out of the Abyss, so it's been a while.
Last WotC module I've ran... nothing. Last time I ran a module it was back in AD&D 2nd days under TSR.
Last WotC module I've run in? One group started Tyranny of Dragons and got two sessions into it, does that count? If you want actual time invested it would be CoS.
