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...

This game is so beautiful. So fun. Thank you Jason. If I can make one suggestion. Can you make it possible to choose upon death to go back to your last home as long as you made a home marker.

Also If I could ask the community to build roads. Maybe try to connect the towns. Make kingdoms and villages. Trade outposts, and homes. So much potential. Happy gaming!

I feel like I am more often born a white person than a black baby. Also, men lack hair diversity. Will there be a hair styling tool in the future? that would be funny.

Its amazing, temp is still getting worked out now, But this game has come so far, and still has a lot in the works. You should definitely at least give it a spin.

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.

Its a fun game. If it works, which tbh with you is a coin toss. Had I known how buggy it was i probably wouldn't have spent the money.

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...

OHOL life is eating, pooping babies, getting stabbed for no reason & being at the mercy of others to heal you ... or not. To become a killer or griefer makes more sense & is valued higher than to contribute constructively.

Update: Temperature Overhaul
February 17, 2019


The problem of temperature in the game was much harder to solve than you might think. The old model was based on a thermodynamic cellular simulation, which would supposedly allow for heat from fires to be captured in rooms and flow out open doors. The model was accurate, but it was based on thermal conduction, not convection (which is much harder to simulate), and the result was hot areas right around heat sources, and cold areas everywhere else, even in enclosed buildings. In other words, buildings were pretty useless for keeping warm.

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.
