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...

One Hour One Life is a wonderful game like no other before it. Please give it a try, I'm sure you won't regret it!

One Hour One Life is an absolute gem in the gaming world. From the moment I started playing, I was captivated by its innovative concept and addictive gameplay. The game's premise, where you only have one hour to live an entire life, adds a thrilling sense of urgency and purpose to every decision you make. It's amazing how such a simple concept can create such complex and engaging gameplay. The gra...

I am unable to update the zoom mod although I have downloaded the latest version (365). When I boot up the mod game, I get an error message that states "The version of the mod is outdated (expecting version 369 - running version 365)" included is the link on where to download, however I do not see a version 369 anywhere on the github.com site. Please assist! Thank you.

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.

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: Rail Buffer
June 2, 2023


I've finally made it through all of the submitted code issues this week, and I've started on the content issues.

You can now put a temporary buffer stop in the middle of a rail line as a stopping point for rail carts, allowing you to stop and load a cart before letting the cart continue onward. Buffer stops can also be used as safe temporary end-caps for partially-built rail lines, allowing you to build a long line slowly over time while still using the completed portion.

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.
