In essence, 7 Wonders is a card development game. Some cards have immediate effects, while others provide bonuses or upgrades later in the game. Some cards provide discounts on future purchases. Some provide military strength to overpower your neighbors and others give nothing but victory points. Each card is played immediately after being drafted, so you'll know which cards your neighbor is receiving and how his choices might affect what you've already built up. Cards are passed left-right-left over the three ages, so you need to keep an eye on the neighbors in both directions.
