Apart from just plain dealing of harm, calamities also have the function of balancing the game by mostly harming larger civilizations more than smaller ones. The beneficiary of Tyranny calamity, however, is chosen freely by the primary victim.

Wouldn't it be more in the "spirit" of the original calamities if the beneficiary was the smallest neighbouring civilization?

Edit: Oops, this should have been posted in the Calamities forum. I'm sorry. Can you move it for me, Velusion?
