The War of Genesis (Korean: 창세기전) is a SRPG series developed by Softmax. The series follows the history of Antaria, a fictional universe where the story is taking place. Even though the developers had stated that the third and fourth installments were spin-offs, they follow the main storyline and have many elements that are essential in understanding the stories of the later games. The Side Stories have a rather different gameplay than that of the original. In contrast to the original games' use of the SRPG type of gameplay, Rhapsody of Zephyr uses a classical Japanese RPG style similar to that of the Final Fantasy series. Tempest also uses different gameplay. In addition to battles, there are mini-games and simulation elements as well.^{[citation needed]}
