7 Wonders is a civilisation building game with the main mechanic being card drafting. The game lasts three ages with each individual player beginning the game controlling one of the 7 cities where the Ancient Wonders reside. Each city has their own unique starting resource and construction path (your choice to follow it or not).
An age involves each players being dealt seven cards from a particular deck with one chosen to be kept. The cards are then passed around for a new card to be drafted until all piles are exhausted, this is repeated for each age. Each card can generate you resources, upgrades, power, victory points or used to develop your wonder. The ultimate goal is to end the game with the most amount of victory points.
