Chill or challenge? It is up to the gamer to set the difficulty. Either way this is a fun game and seems to be a labor of love for the author. I recommend this game to anyone that likes survival and city build without zombies (Ha, ha, ha). It's still is colonial to medieval and much like how we got to where we are today. EZ to learn controls and weather system as well as speed-up or freeze time. More features abound, give it a try today!
