I haven't bought* the 2024 DMG yet, nor anything else 2024, so I can't speak to anything in there other than what's quoted in posts here. I do have the first 4e DMG (of two? three?) but it's a long while since I looked at it.
But now I'm curions as to what other guidelines and limits they're laying down and whether I, as something of an anything-goes player and DM, would see anything the least bit useful in them.
* - and likely never will, I have the 2014 core three which would seem to be close enough; similar to my not buying the 3.5 books as I already had 3e.
You can find the core of the guidelines available for free on DnDBeyond. That’s where I’m quoting from - I bought TOV instead of 5.24!
