This one I had almost forgotten. Alganon finally launched its long-awaited Rise of the Ourobani expansion this week. The expansion was announced back in June 2011, but news has been a bit scarce for the last two and a half years. That long wait has finally ended and the expansion is now live, adding the new Ourobani race, the new Warden class, the continent of Aeon, flying mounts, an alliance system, and more. Players can take advantage of an "early adopter bundle" for the next two weeks to get the expansion a bit cheaper at the price of $17.50.
Patch notes for the expansion are available on the Alganon forums.
