As someone in their late 20's, it's becoming increasingly more difficult to gather friends for activities that:
a.) Don't involve staring at a screen. I do that enough every day. All day.
b.) Doesn't involve eating &/or drinking as the primary activity.
c.) Is more than just "passive consumption" of someone else's hard work (theater, media, sports, etc).
Dungeons and Dragons really "scratches" this itch. It's a creative endeavor, where the ultimate goal is just to hang out and have a good time.
Maybe it's just an excuse to hangout, "shoot the shit" and get some laughs in? Or maybe it's a much deeper creative/intellectual endeavor.
Either way, it's been one of the best additions to my life in recent years, and it's gotten me to do a lot of thinking about the nature of creativity and the idea of crafting "fun".
