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 love this game for several reasons.

1) It is fast. Lot of things happen during your one hour life.
2) There is a lot to discover. You can experiment, learn from other players, teach, read on wiki.
3) It is cooperative and you need to communicate with other players. Player base is very helpful.
4) Original things: Message length depends on age; players spawn as other players bab...

The game is just amazing. It's ever evolving and while Jason the dev may mess up stuff from time to time he usually fixes it up. You can sink hundreds of hours into this game and it's definitely worth the 20 bucks!

Good game! Really fun and good people. Of course you'll find the occasional griefer here and there, but any good game still has people who not everyone will agree with. It has a nice vibe and is inviting to me. I will play this game for a long time. Even when there is a griefer present, I don't find it that annoying, but there are ways to deal with them and I think that's great!
It is never d...

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...

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.

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

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 ...

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...

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: War Report
September 13, 2019


I'm back from PAX West with a bunch of bug fixes and improvements. The arcs have generally been pretty stable during this time, lasting one to four days before we get down to a single family. I'm still not fully satisfied, and I'll be putting a lot more effort into making it even better in the future, but this is a good place to turn my attention to other matters, namely the enormous list of user-reported bugs that have built up. This week, I got through all of the reported and reproducible code bugs. Next week, I'll be tackling the list of content bugs.

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.
