Years ago a d20 publisher wrote something to the effect of, "How can you be a writer of role-playing game material if you aren't playing the games you're write about?" Well said! With that in mind, I had a chance to test out one of the articles that will appear in Loviatar No. 2.
Overall, the experience went very well. Based upon my players' actions, there is probably more information than a GM will need, I feel it's better to have too much information than too little, though. I am a stickler for detail, I guess. Also, I noticed that some of the Perception check DCs were set a bit too high. There are some interesting bits of trivia scattered about the house. If PCs are unable to find the nuggets, then what's the point? Therefore, I adjusted the DCs downward to allow the PCs a better chance of gaining insight into the workings of the house.
All in all, the article is solid and I think you will enjoy it a great deal, regardless of what edition of D&D you play.
