This is THE best Solo RPG tool I have read. (And I have read them all) I have tried most solo systems to play freeform but always feel I would like to play actual written modules as I always find freeform so much work and fall into the same boring routines. This system gives you robust rules to play published adventure modules with a single PC and a sidekick. The enemy AI section is great in this book and especially good is the idea of default behaviours for your PC. The rules about changing the adventure difficulty seem great and the Immersion role to set the scene is very clever. There are also rules for chases, and selling gear. I am going to make my next combat the finale of my current game so I can use DM Yourself properly. If you are into Solo playing this is a must buy. I can't find a single fault in this product.
