First, quality is at the rendezvous. the board is superb, details are impressive finesse! The booklet containing the rules, is large (28 cm by 28 cm), it has the hardware, the development of the game, the course and rules. It contains eight pages. The understanding of the game is simply to both see the first three rounds. The box contains therefore, after the tray and the rulebook, cubes gray painted wood (stone), brown (wood), light (sandy), blue (iron, precious because rare) .They are all packed in plastic pockets with zip, except for blue cubes (?). The rest of the chips representing the builders, workers, handlers and against marqueurs.La paint on the wooden parts is clean and does not go away after several uses .An Dé for taxes (which has no 1, 2 mini gold for the King :). A package of reduced size cards, which does not hinder the handling and finesse reminiscent of tray designs .And of course, the Cathedral, which is in six parts. For each piece of the Cathedral, is a .So game round you have understood the game is won in the sixth round. The goal is strategic, build the cathedral managing resources in the region, employing craftsmen, or not pay taxes, buy and sell, while preventing any other playmates to get rich (no or few resources ) and take maximum points win. Of course, as in the book, jealousy and the vagaries of fate are there !! to spice up the towers, the top! With two players, it's very nice. At three and four, the game takes on a special dimension that we "feast". The game is played between 30 minutes and 45 minutes max. In short, I advise you to spend pleasant moments of relaxation and think without taking themselves seriously. I have not played with the extension.
