How about this?

Graal

I think that one's good. Simple, and to the point. As for representing Graal, the game means something different to everyone. You could use the RC icon, as that's what most people see if they stay on Graal long enough. The people who play Graal are plagued by profanity and violence, so you could include that in the logo. It would probably be most wise to go through some reform before making a logo.
