Cardmaster: Adventure Design Deck

From BoardGameGeek:

This game can be loosely used as a role-playing aid or as a really basic dungeon-romp for several players. The basic mechanic is building a dungeon by using cards and defeating monsters for their treasure. The game comes with a couple of basic "quests", but most of the replayability is left up to the owner. There are three decks of cards present: - The Location deck consists of corridors and rooms that are used to assemble to actual dungeon during play. - The Monster deck is drawn from to determine possible encounters. Traps are possible. - The Treasure deck is used to give out booty to adventurers that defeat monsters. Traps are possible here, as well. The game is very simplistic and could easily be developed into something much more advanced, but it is rather fun and can easily be played solitaire.
