Each of the eight alignments in Genesis contains eight respective races, for a total of sixty-four races in the game. All races are humanoid, though they can have animal-like features that distinguish them from beasts. Only one or two races have been created for Genesis, and the rest are based on traditional mythological races. To keep the game balanced, each alignment has at least one race that can fly, and at least one race that can swim well and breathe underwater. Also, each alignment contains a variety of differently sized races. These races range from the tiny races, which can be as small as 1 foot (0.3 m), to the giants, which are 15-16 feet (4.6-4.9 m) tall. Flying and swimming races are of average humanoid height. All heights are displayed in the table below. Lastly, players can choose to play as Elementals, which grow in size based on their experience and power. Elementals, however, are identical to beasts in many ways; they cannot equip items and lack certain other human traits and abilities.
Giants and other large races are penalized in various ways to make up for their great stength. For example, they eat more food, they require more resources to build their items, and they are typically less intelligent and agile then their smaller counterparts. Additionally, they have trouble fitting in small spaces. Alternative names some races are given in parentheses.
