Might not be related to Second Life, but with so much hype around the game, it only made sense to share it here. Rift is a MMORPG by Trion Worlds.
The game is based on the concept of sealing rifts that appear all over the world of Telara. Sealing the Rifts is a quest in itself given the multiple stages gamers have to go through in order to completely close the rifts. Unlike Second Life, the game offers 4 classes with abilities to set them up with. Incase you’re interested in learning more about the game, details could be found at Rift Guide.
