Maeshowe is a solo print and play game about tomb robbers in AD1150. From the game’s description:
According to the Orkneyinga Saga, Earl Rognvald Kali Kolsson broke into the chambered tomb of Maeshowe, on Orkney, in AD1150. In AD1153, Earl Harald Maddadson and a group of his men sheltered there during a snowstom. The sagas tell us that Rognvald found treasure there and that two of Harald’s men went mad. When the Victorians opened the tomb in 1861, they found Runic graffiti demonstrating that both of these episodes were based on real tomb-breaks. This game combines the two events from the 1150’s and casts you as Harald and Rognvald.
