Age of Sigmar will be an easy and "cheap" introduction for new People and the first Release of the new Edition. Soon after the Set GW will release the Full Rulebook with full skimisher and standard Rules. Later in this Year, there will be a classic Starter Set like the previous with two Armies and a Full Mini-Rulebook.
