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 think the token (life) amount needs to increase. Here I am waiting 10 minutes for a life. It just occurred to me that I play this game because I need more irl friends..since I'm literally waiting to 'get a life'.

Too few lives equals sadness-especially on 'Friday Eve Runs'. Now, I just have to watch YouTube. I could be mining for gold if I had more lives...

What was once one of my favorite games of the year has turned into somthing that I can't even play without getting really angry.. people stealing stuff the ungodly amount of TROLLS that just ruin everything they touch.. You'll never see any huge cities or cool stuff becuase people can't go two generations without leaving even the best towns in ruin.. this game brings me no joy anymore.

Good game, but the frequent reworkings and updates make it unpredictable. I enjoy the premise and the experiences I've had in it throughout my time, but it's definitely not for someone who likes stable, consistent gameplay.

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.

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.

The game is finally adding more game-play content, I approve of more domestic animals, and the surgery addition is also welcome. I still feel like the game needs more structures and a better way to locate nearby towns (bell towers are a joke) maybe establish trade and migration like the good old days where you had neighboring villages, and carpenters who built roads connecting them.

Ok, so I got this game and loved it but the new life system sucks. I get the point of it but when the Tutorial counts as a life I draw the line.

Persona l I never like this update because it gives griefers a HUGE advantage because they can basically kill you for an hour and in the start of a life you are completely helpless. You can't even curse a griefer because you are to young and can't t...

Since we get more players in this game, the game become lag as hell. Optimization didnt not work, I found this game great but I cant play laggy as hell or can take to be disconnected because servers can handle so much ppl. I dont think it will improve, if you are thinking about buying this game, get a time machine and buy it three months ago, when it worked great. Its a shame such good game has th...

I cannot recommend this game to parents with impressionable children, which is basically all of them.

When I bought this game, it was promoted as a group activity for progressing thru stages of civilization while trying to stave off or outrun concurrent waves of resource shortfalls. I enjoyed this aspect of the game.

However , the developer has released a number of updates that incre...

Update: Lots of Fixes
June 14, 2019


An update like this is long overdue. Thanks to all of you for reporting everything you reported. As a result, a pretty long list of issues had built up. This week, I got through all of the known and reproducible issues affecting the game engine and code. A few bigger fixes are worth mentioning specifically. If you've ever seen a "ghost" player standing there, aging, who no one else can see, the source of that problem has finally been found and fixed (it was caused by someone passing through your area, going at least 64 tiles in one go without ever stopping their walk). The issue with animals and other movable items not respawning when nature reclaims an area has been fixed. And most importantly, a server message overload that was triggered when you targeted a family member with a sword has been fixed. That overload was so extreme that it caused nearby clients to get bogged down and disconnect. A full list of the changes can be seen here:

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.
