I have a phenomenal D&D 5e GM. We’re on the third campaign (with some folks coming/going… me and the DM are the only ones that have lasted the whole time). It’s a homebrew world with bits and pieces borrowed from all over.

But what I find really fun: each campaign has been separated in time (1 -> 2 was many hundreds of years, and 2 -> 3 was a few decades). He’s been able to weave our past exploits into the lore and mythology of the world. In campaign 1, our characters ascended to godhood to replace the old gods that had died out (causing all sorts of chaos in the land). Now there are churches and sects and secret cabals dedicated to them. There are also times when I have to remind myself that my character doesn’t know everything that I know! There’s this one immortal wizard who keeps coming back to taunt us like Q in Star Trek: TNG, but each new campaign, I have to play dumb while secretly shaking my fist.
