In this question I asked a pretty specific question which I think can/will/is generating useful answers. However some of the comments (before they were removed) suggested that, incidentally, Curse of Strahd was a poor choice.
I know game-recs are offtopic, so I can't ask "What's a good starting adventure for first-time players and DMs?" And "What do I need to know DMing DND for the first time?" seems pretty broad. Would "What do I need to know about running official DND5e adventures for the first time?" fly? Or do I really need a forum for what I'm after?
