I have only recently started using this deck and others to start playing a solo game but I will jump in in case anyone else is confused as to what this is or is not. This is not a game system it is a deck of cards you print out and use to generate a dungeon including the chances for encounter and events one room to a card. You need a set of RPG rules to resolve the events that unfold. It can be used universally however it seems less work to use with retro clones but I haven't tried it with enough systems to say that with any certainty yet. It is very much like creating a dungeon using the tables in the back of the 1st edition DMG but with all the chances for things on one card and no game specific things.

Outdoor 3d cardboard props and mini's also includes an advenutre that is a continuation of the plot form the dungeon/indoor props in The Kidnapping of Princess Ariana.

For the D&D rulest these are merely lists of monsters by level and a list of random treasures can save some time from roll them yourself from the tables given in the B,X,C rulebooks.
