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...

A GREAT GAME - ZH-CN (13.9 hours on record)

One Hour One Life is a great game. It's addictive. Fertility, growth, death. Every step is full of surprise or sadness. But it has a drawback - it doesn't support Chinese! What to do? We made its Chinese version and were able to connect to the official server.Email me at is.52hertz@gmail.com .

I really love this game and will always play it. That being said the game is getting stale due to two things. The first thing is the road, I liked the game so much more before they added the road, everyone is just way to close together now. There isn't even any war anymore so being close just sucks. The second thing is that the servers just don't get reset enough. I haven't been in a town that doe...

No life is ever quite the same. Some things are complicated (playing on Mac, well progression, specialty biomes) but once you get over the learning curve its a lot of fun

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.

BUYER BEWARE (96.6 hours on record)

This game used to be a lot of fun. Then the creator decided to axe free will from the game. So what if a player chooses to steal, destroy, or kill? That's a part of real life, and should be in the game too. Instead if a player does or says one little thing another player doesn't like, they are cursed and immediately relegated to Donkey Town on the next play through, sometimes a ban lasting several...

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: Worm Farm
September 22, 2023


Many fixes this week, including domestic production of worms through compost piles and mass-transportation of worms in buckets.

You can now cultivate willow trees and bald cypress trees, though only in swamp areas. But these are the only trees in the game that can be cultivated without irrigation.

You can cut a rope back into its component threads. You can remove cool glass from bowls and stack it.

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.
