This is so charming! Creeping around the baron's estate is great fun, but darn are those puzzles difficult (to me, anyway) (also, I'm pondering how to keep replayability once the puzzles are solved). I wish there were a PDF laid out for saddle-stitch binding.
Captures the feeling of the original novels. Easy to use. The rules for ship and unit combat are an excellent and unexcpected addition that lifts the Lords of Mars on to a new level. Simple art is just the final icing on the cake. I recommend!
