It's still D&D with elements I recognize being in the game from more than thirty years ago. Is it the same game today that it was when I started playing in 1987? No. But that's okay because I'm not the same person today and I doubt the same game would appeal to me. D&D lives on and it will continue to change so long as it lives. It's entirely possible it might change, or I might change, and I no longer want to play. But it'll still be D&D.
