A friend of mine started to run Curse of Strahd as a Professional DM. It's an iconic supplement, but it also has a LOT of problems and could be done so much better. After reading just the first few pages my friend was ecstatic, "One page in and I can already tell this is going to be 10x better than the original."

If you enjoyed Curse of Strahd but want a fresh, new, inspired take then She is the Ancient is the way to go. I highly reccommend it to any group.
