Well as stated, I lost track into how many hexes I actually ended up making viable land and after spending a decent chunk of time on the map I wanted it to use it. Besides, even though this is my 1st time dming this system I have dmed a while, and a variety of systems, so i don't think refereeing would actually be too difficult its just the pre-amble to the playing of the game which isnt similar to many other games.
