Medina is four player city building game. It's a purely abstract
game, but as with any multiplayer game, there is a certain element of
uncertainty because more player's actions affect the outcome.
The official rules are here,
claim four palaces, and score points
for the size of the palaces you own, plus extra points for palaces
adjacent to walls, and palaces adjacent to meeples. The trick is
that all the palaces, walls, and meeples are not owned when they are
played. Strategy for the game revolves around when to claim your
palaces, and playing pieces that benefit you more than other players.
Medina can also be played with 3 players. At Boardspace, you can
also play with 2 humans + a robot or 3 players plus a robot.
Robots: This is a
difficult game for the robot. Most likely they are only going to
be useful as fillers, not as credible opponnents.
