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...

Murderers ruin all (239.0 hours on record)

It's really sad when twenty generations of work is ruined by someone who murders your entire line. Good game though...just damn griefers.

Best. Game. Ever. I had four sons, Jeff, Junior, Mike, and Fred, and I had to say goodbye and good luck to them. It was absolutely heart breaking, and I don't want to do it again, but I know I have to say goodbye to make progress and evolve this world, so that is why this game is heartbreaking, yet fun at the same time.

I love you Junior

Goosey The Goose (11.3 hours on record)

I was born into a thriving town. Suddenly everyone died. I was all alone almost my whole life in a ghost town. There was a goose in a pond in the center of town that I named Goosey. I spent my days keeping the farm alive and attempting to learn how to make fire to keep the ovens on. At the end of my life, I gathered my bounty of carrots and corn and sat by Goosey and chatted with him about the cur...

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

Sad game (444.2 hours on record)

This game describes the love of mother and family

Nobody can live forever and their life is limited.

The only thing player can leave is their bone and what they've made.

But what in earth do they've manufactured or harvested good for themselves after death?

It barely effects players next game so It means nothing as well.

Everyth ing is meaningless afterlife then ...

It's a good game but honestly I just wanted to see how many hours I have

New update is awesome. The game is very balanced currently. If you're considering getting the game, I highly recommend playing as an Eve and learning the basics. Go into the game with the expectation of dying young and dying often.

This isn't just a game. OHOL will teach you more about the human condition than any book.

This is a must play for anyone with a passing interest in phil...

New update. Make stews and farm cool shit!

It's a great game where you have one hour to play one life. Your goal is to build for the future. Make carts, farms, hunt, get sheep, run from bears. There's loads to do and learn. Name your kids and watch your line go on for generations. New content gets added weekly. Try it out. Still playing after 350+ hours so I'd say it's enjoyable ;)

this game has been taken over by trolls. not fun anymore when punk kids run around stabbing everyone and killing the whole town. need a way to ban players for bad sportsmanship. or put bounty on their head.

Greifers are ruining this game. The stabbings are getting bad, and what makes it harder still is you still can't defend yourself even if stabbed. I've been murdered after trying to catch the greifer and because I was wounded first I couldn't finish them off.

Update: Good Eating
June 15, 2018


There's now a good reason to eat all sorts of delicious foods, instead of just mono-gorging the most efficient and convenient food. Omelettes and tacos and kraut and stew. And even more reason to share food and meals than there ever was before, and hopefully a good reason to have a village chef that might coordinate all of this for you. Tuesday is taco night.

This update adds a YUM mechanic, which gives you a bonus for feasting with a long chain of food variety. The more variety you eat, the better you feel. So let's eat beans for every meal! Er... yeah, so plain bean tacos do get a little boring. Future updates will add some toppings to spice things up, and maybe even some slow-cooked carnitas. Get your limed corn ready, people.
