Rather than just purchasing units at certain structures, it should be noted that there is now a starting point, or base, where you will be able to select your units and swap others. Another interesting way of unit accumulation is to visit local towns and search for volunteers to join your forces. Unlike the previous 2 WarCraft games, where you chose from Human or Orc, WC 3 will be featuring 6 new races. Currently only Human, Orc, and Demon are the known races at this point, Blizzard has yet to reveal the other 3. There is a major decrease in the need for resource management, as the only available resource that is of any concern in gold.
