There is a single-minded attention to quality with these books that really carries through. Clarity, precision, faithfulness to the original (except in rare cases where the original could use a fix), and ease of use are all doggedly pursued and achieved. The companion is completely compatible with the original Labyrinth Lord and if you intend to play 'Advanced' style in fact you really only need this book. I am extremely grateful for this meticulous work of Goblinoid Games. I researched numerous retro-clones and this was far and away the best for the above reasons. The excellent 'hobbyist' style art really takes me back as well!
