15 Días: The Spanish Golden Age
This is a fascinating card game, not least because it combines team and individual play. Each round players compete for points in three facets of the Spanish court, using the cards they have available. Of course, one of the things they're doing is tuning the cards they have in play to maximise their chances.
However, the players are also divided into two teams (the two families struggling to be the new King's prime minister). The teams fight it out first each round and then the players compete individually. Hence the need for an even number of players to balance the teams.
