It is a very unique experience. Its one giant puzzle and the community is pretty active. I don't do any role playing, but the role players add a lot of depth. The story is good, and the artwork is good too.
I quit for a couple years, because I was stuck and couldn't fully appreciate the challenge and it drew me back. That time I was able to figure it out. I am back again and maybe I can make it into loreroot this time.
