A box of blocks. I would recommend being careful allowing kids on a public server, but the game can be played solo, and a smart parent with the resources could set up a controlled server, for the child to play online with friends.
Sweating sickness, also known as English sweating sickness or English sweate (Latin: sudor anglicus), was a mysterious and highly contagious disease that struck England, and later continental Europe, in a series of epidemics beginning in 1485. The last outbreak occurred in 1551, after which the disease apparently vanished.
Death often simply seemed to occur due to dehydration and exhaustion. The sweating sickness first appeared around the time that Cromwell was born, at the end of the Wars of the Roses. Some believe it arrived with the invading army of the first Tudor king, Henry VII, in 1485. By the time it disappeared in 1551, it had caused five devastating outbreaks.
