This game is about playing one small part in a much larger story. You only live an hour, but time and space in this game is infinite. You can only do so much in one lifetime, but the tech tree in this game will take hundreds of generations to fully explore. This game is also about family trees. Having a mother who takes care of you as a baby, and hopefully taking care of a baby yourself later in life. And your mother is another player. And your baby is another player. Building something to use in your lifetime, but inevitably realizing that, in the end, what you build is not for YOU, but for your children and all the countless others that will come after you. Proudly using your grandfather's ax, and then passing it on to your own grandchild as the end of your life nears. And looking at each life as a unique story. I was this kid born in this situation, but I eventually grew up. I built a bakery near the wheat fields. Over time, I watched my grandparents and parents grow old and die. I had some kids of my own along the way, but they are grown now... and look at my character now! She's an old woman. What a life passed by in this little hour of mine. After I die, this life will be over and gone forever. I can be born again, but I can never live this unique story again. Everything's changing. I'll be born as a different person in a different place and different time, with another unique story to experience in the next hour...

Was born into a village of two women and five men. Was named named Eddi by Grandma right before she passed. Things were pretty great. Cousin Eddy Plant taught me to be a wheat farmer. When he died, I buried him. Aunt Luna gave me a psychadellic mushroom, which was hilarious. It made everything on the screen glitch. She died laughing at my reaction. We buried her and mom side by side. Then, we real...

I love this game, but the lag is making it borderline unplayable.

Very good game I would recommend to any people who like survival. Living in a civilization that your helping to build is good.

Super fun game loving it so far! Just wish we could find other settlements more easily. I know if a town has a bell you can follow it but may a map could help?

its a fun, simple game, with a complex strategy
lot of drama, lot of bad players, lot of griefers and murderers, so will annoy you a few times but can be so fun, very original concept and jason works on it frequently, each update changes everything but its in a good direction

The big farm update is the best update so far. I love sharing stew with my family. It gives me time to spend more time with my children and makes the game not feel like such a rush. It seems the game culture has improved because of it.

First I bought on Steam and realized there is no Mac version. Spent another $20 to get on Mac. Then I had hell getting the game to run. I had to go to the shell and run manually. Then the wall blocks you from moving to the fire and kindling so I'm stuck. $40 to play the tutorial for a few minutes. How can I ever get past the tutorial and play the game? I restarted 3 times and I have reinsta...

Since we get more players in this game, the game become lag as hell. Optimization didnt not work, I found this game great but I cant play laggy as hell or can take to be disconnected because servers can handle so much ppl. I dont think it will improve, if you are thinking about buying this game, get a time machine and buy it three months ago, when it worked great. Its a shame such good game has th...

User Story: The Tale of Scott Silverthorn, by MaggieMurdoch
October 30, 2018

this is a tale of one of my last lives, sometimes I live very mundane and uneventful lives but other times I find one that stays with me and makes me think about it...This was one of those lives.

I was born a baby boy to a woman named Samantha Silverthorn in a tiny settlement, as I was born my older brother Lason was visiting, my mother had six children before me and had one after me, surviving to adulthood there was only me, my big brother Lason, my big sister Freyja and and my younger sister Liza. When I was born my mother gave me a single snake skin boot.
