I recommend RogueWatson for DMsGuild reviews:Candlekeep mysteries was underwhelming enough I did not bother with Radiant Citadel. I am curious about the Keys anthology, mostly whether they will actually be "heists" in any useful meaning of the term.
People say stuff like this all the time and all I can say is that there is no way to know whether anything there is good or not. There's too much material and too few reviewers. Plus, honestly, have you EVER seen someone mention a DMsGuild adventure in discussions here? It doesn't matter if they are gold if they are impossible to find.
