Secrets of the Tombs was clearly designed by Martin Wallace to be sold in the British Museum's gift shop. As such, it contains lovely components, including cards with photos of actual Egyptian artifacts and educational text descriptions. Other cards, if you bother to read them, have information about Egyptian mythology. I would expect a game like this to be a dreadful roll and move affair, or possibly a dreary set collection game. Surprisingly, there is actually an enjoyably trashy game in the box.
In Secrets of the Tombs, players are archeologists, or perhaps just tomb robbers, racing to be the first to collect a certain amount of treasure and get out of the tomb alive. Like DungeonQuest and The Adventurers, it is absolutely possible for all players to die, and for everybody to lose the game.
