The biggest drawback of this game is the fast time limit, it should be cut be 10~20%. And the lack of a good strategy guild tutorial. It's an aggravation that spoils the fun factor.
It would be good if the gains of one game could be passed on to the next level for more challenging monsters, robbers, etc., past the building options.
As it is it's just an embellishment of the previous versions. And how about being able to name the players.
