I am a big fan of sources like this which fit a dungeon onto one page, and I especailly like the dungeons which were desgined. They are simple to use and the monsters seleceted/made all fit perfectly with the the dungeons.

Although I did like the old school layout I did think it could have been finessed abit more to better fit in the information of the dungeon, and the monsters. Having the monsters on the same page would be even better. Like wise a bit more fleshing out of the narratives would have made this perfect, but there was enough for me to easily build into. Will be running one of these in my next session.
