While arguably surpassed by the rise of OSE and its Advanced rules option - this book remains vital for anyone interested in a B/X style 'Avanced Labyrinth Lord' retro-clone. Its layout and text may not suit some, but I find it a very useful resource for rules, monster ideas and options and other inspirations for my games. I like the art choices and this editions cover is phenomenal. I can't wait for a second edition when it is ready. (So is the Otis cover too.)
