The Rohan-Dale union in a sort of a new kingdom is interesting... I would just say that these reunion projects generally have a potential gameplay problem : they usually propose for condition the destruction of an evil faction, in this case it's Rhûn. What will the kingdom of Rhovanion be good for without a strong ennemy that makes the game worth playing it ? Is this all about a nice window saying "victory is your, congrats, bye" ?
