Sins of a Dark Age was a fantasy MOBA game made by the creators of Sins of a Solar Empire. On June 30 2015 the developers announced that further development had stopped, and the servers were eventually shutdown.
Sins of a Dark Age follows the typical trapping of games like Dota 2 or League of Legends with some specific twists. The first twist on the gameplay is "realm quests" which is a system to try and force players into combat with one another more often. Another system that has since been removed was the commander system, in which one player takes control of the minions, which in other games are typically AI controlled. This idea has been removed as the developers felt it didn't work.
