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...

Everybody helped me, I lived to 40-odd years old (I think I got disconnected right as I was about to die), and I was just about to learn how to feed sheep. NEXT TIME!!

This game is pretty awesome! While quite of few people get jaded of it after some time, people like me can play on and on, enjoying the practically endless possibilities! The art is fun, too, and the interactions, physics, and pretty much everything is fantastic and fun. Thank you, Jason!

Although this game has it's flaws, there is potential.
There are many things I disagree with, but I am curious to see where this game will go in the near future. I would like to see a difference between the wood that each tree produces for building, crafting and so on.

Im sure my hours speak much about how much I like this game. To be honest I wish I could put it down some times but I cant XD

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.

I really think that this concept is very interesting.

I mean, a game where you literally evolve from nothing and leave with nothing, but leaving something (simulating real life) is amazing.
I have nothing bad to say about this, it's just amazing.

Than k you, Jason, for making this lovely game, and thank you to every single player who does their best to help the communities survive!

Great game to play, every life is unique! Sometimes you play with annoying children who wants to stab everyone.. but most of the times you will play with nice people who want to play the game and can learn new people things.

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...

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

Left the game for a long time. Came back and only certain races can go in certain biomes? There are tool slots? What the hell happened to this great game? I used to love it, I don't know if I can recommend it as it is now...

I can't play the game correctly due to wolves appearing as plates, and vice versa. Your discord server is full of shits who won't help because of dumb grudges from a completely different place. I don't recommend the game due to griefers, and I 100% dont recommend the discord server.

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
July 24, 2020


I spent the week clearing up some of the reported issues that had accumulated.

The biggest change is to how killing and posses work. First of all, if you try to join a posse, but cannot for some reason, you get a DING message explaining the reason.

Next, there's a new exception to the posse and exile requirements---something like "live by the sword, die by the sword." Someone who kills becomes vulnerable to being solo killed, without being exiled or having a posse form against them, for 60 seconds (the same amount of time that they are stuck holding the non-sword murder weapon). This helps people deal with the "evil leader" problem. The current leader is the most powerful in terms of being able to exile, which means that dethroning them requires quite a bit of political willpower. If that leader goes on a unilateral killing spree, organizing collectively to de-follow them---to strip them of power---can be really difficult. One of the early ideas for justice in the game was "safety in numbers." As long as the citizens outnumber the griefers, the citizens should triumph. That idea resurfaces as we differentiate good killers from bad killers. The good ones will need to be protected by others while they are in their post-kill vulnerability state. The bad killers, who are acting alone and without the approval of the group, become fair game for everyone. The 60 second window of vulnerability is a live server setting, and may be tweaked in the future. It could be even longer than the murder weapon hold time.

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.
