Yeah, I think Morocco might be my most interesting civ to play with from the new ones we know. I do hope I'll start next to a good amount of City States when playing as them - I'd rather have them have the +2 gold then rival civs.
Their improvement is interesting. I wonder at what point in the tech tree it comes though. Seems doubtful you can do such at the beginning of the game. Same time as Forts?
Their UU however doesn't interest me terribly much. Oh, it'll be good, but nothing too great, I'd think. Have to see how big the bonus is first.
