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 grandmother'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 grandmother and mother 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...

Great game, would recommend it. Every game is different but the same at the same time, its great.

Probably one of the better games you can ever play. Hardest part is learning, then unlearning, then relearning whenever things change. Hours speak for themselves.

This used to be one of my favorite games, with my hours as evidence, but I can't say the same now after the new "arc update"; with all the players crammed together and sharing finite resources in a tiny little hell box. Everyone is frustrated by the baby apocalypse and lack of progress. It's a constant scramble for food (if you survive infancy) so things can't really get done anymore. I would only...

OH, PLEASE.... You've got to upgrade user interface in this game first. Make NO MORE complicated rules and stuff. I am tired to get new ppl to know some rules such as like hierarchical leadership shit or freakin yum system. I think only few players read your update news or forum, but many players get infomation IN THE GAME. You should know that. Sorry for the English. cause I don't speak English. ...

The sword was the most fun thing in the game, even after the shift-click update. People were joining raids and having the best lives they had had in the game while doing so. I loved it and I lead maybe over a hundred wars and raids on towns. Then the rift came, causing the crafting players to riot and grief the life out of it, giving us a moment of freedom when it was lifted. I even made a map in ...

Update: More Fixes
December 19, 2020


I'm working through the list of reported bugs.

When picking the fittest follower to inherit a leadership position, exiled followers are no longer considered. Special biome/homeland boundaries no longer line up with ley lines for natural springs. Multiple DING messages, occurring at the same time (or in quick succession) are now queued, giving you a chance to read each one in turn. This means that if you inherit both leadership and ownership at the same time, you'll hear about both. A victim's fleeing emote is correctly preserved when they step in and out of a bad biome. The language specialist family is no longer accidentally fertile outside their homeland band, to the far north or far south. A gap has been added between the desert and jungle bands, since having those bands abut each other creates an impassable barrier for folks who get sick in both. And finally, the second phase of the tutorial has been re-designed somewhat to make it less confusing for new players.

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.
