I'm in a group with a bunch of folks that are professionals in their field in their late 20s to late 50s and it's the exact same reasoning. It's all in fun and isn't thought about too much

I know my DM uses /r/ghostsofsaltmarsh for our campaign there. I think having a sub like that with resources and suggestions would be helpful kind of like a more specific DM academy page that would keep "spoilers" contained

I would love to see some discussion threads about official content/news. I am vaguely aware of the books coming out, but it's hard to find full threads and discussions on the Giants book or the Book of Many Things with speculation based on the UA and what we've heard (or even leaks if allowed)
