Question: What do Stonehenge and Kamisado have in common?

Context paragraphs:
Stonehenge (game): Stonehenge is the first anthology board game.  It was released in June 2007 by Paizo Publishing under their Titanic Games imprint.  Five game designers, Richard Garfield, Richard Borg, James Ernest, Bruno Faidutti, and Mike Selinker, were given the same set of game materials and each created their own game using those components.

Kamisado: Kamisado is an abstract strategy board game for two players that's played on an 8x8 multicoloured board.  Each player controls a set of eight octagonal dragon tower pieces.  Each player’s set of dragon towers contains a tower to match each of the colours that appear on the squares of the board (i.e., a brown tower, a green tower, etc.).  One player’s towers have gold dragons mounted on the top, while the other player’s towers are topped with black dragons.
