Been watching a few different playthroughs of a game called "Wildermyth" on the ol' youtubes - although the mechanics are obviously different, it gives me a very vintage D&D vibe. Stumpt's playthrough is one of the playthroughs with a little more of a lighthearted vibe in the multiplayer, which was what really kicked me in the 'old D&D' feels. Definitely a game I'm keeping an eye on for eventual purchase.
