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...

I really loved this game. It was really relaxing playing this game and funny not to know weither or not your genealogy will survive. Or maybe someone one day will find this camp and use it. It was the legacy that was important. But since you closed this world, i feel so frustrated every time i play. i bump every life on the four corner of the map. i feel trap inside.

Swor ds, Family, and far to many bears.

I still remember making my first arrows, and a bow, and a backpack, and bear hunting.

I killed my first bear many months ago, the third time i played, and It was one of the first bears killed. This was a long time ago.

My family here was killed by bears, in this new update: with fissures, soup, walls, f...

I love this game so much. It might seem boring to those who enjoy games where you play as a single character throughout the game. But this game really is a challenge. Trying to start up a successful family tree. But you'll never know if they managed to keep everything alive unless you check on the site. I wonder if we will ever get up to generation 300.

Review 2: The game is still amazing...

While ohol is not a perfect game it is an ever evolving game. Jason is taking steps in the correct direction to try to fix some of the underlying problems with the game and that's great.

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

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.

Extremely disappointed to have returned back to the game after a year gap (due to family issues rather than the game itself), although now because of this 'rift' update, it very well could be another year gap (this time because of the game). What an absolute shambles! Everything the creator wants this update to achieve is pointless, as everything goes against it! Honestly, I've never met so many p...

I really enjoyed this game, not so much now. The rift is a dumb idea. You can't even throw things off of it (like dead bodies). Feels claustrophobic now. Property fences keep locking me out of my settlement even though I have the same last name. Not a fun experience right now.

Update to my previous review:

The game in its current state means that you will not get to play. You will be born. There may not be a mother who can feed you and the dozen other babies crying for a teat. Depending on the "arc" being born as an Eve may or may not be available.
You no longer have the choice of playing this game when you want to.

Yes, negative reviews will wake me...

Update: Whole New World
August 3, 2019



Thank you all for bearing with me as I continued to adjust and perfect what is now the most massive set of fundamental changes in the history of the game. Like I said in the last update, we got off to a very rocky start, but by the end of this week, it was almost completely smooth sailing.

Containing all player activity in a bounded area, instead of letting it spread infinitely on the map, revealed all sorts of problems, particularly in terms of resource distribution, settlement locations, and griefing. On an infinite map, there are always more resources available if you walk far enough in any direction, which is what people used to do to find settlement locations, and you can also easily hide from trouble-makers in the vastness. A bunch of important features in the game, like fences, were rendered unnecessary by the unbounded map.

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.
