Perhaps surprisingly, /r/dndbehindthescreen. They're one of the few subreddits I've found that has a subscriber count in the tens of thousands, consistently high-quality content, and an active community of people that actually contribute. /r/roguelikedev is a fun community, as well- I love the opportunity for cross-pollination of ideas, since everyone's doing a rather similar thing, but with different languages, libraries, and so forth.
