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...

All the world's a stage,
And all the men and women merely players.
They have their exits and their entrances,
And one man in his time plays many parts,
His acts being seven ages.

Pretty fun but the controls are crap and it's far too zoomed in, you can't see anything around you. It takes a couple seconds to redirect after moving the mouse and you can't see dangerous animals until they are right next to you. It needs to zoom out and use WASD or arrows to move. I've died with food in my hand just because i couldn't decode the right button combination to eat.

This is a great game! It is very fun to play, but it can get quite challenging, especially for new players. I recommend watching a few YouTube videos and reading at least one online tutorial before you start, because going into the game with no knowledge of how anything works is deadly.

This is all I want to play. Your choices and actions matter, and the relationships you form are really fun! Be prepared for a massive and complicated tech tree. Very steep learning curve. But there are always players who enjoy teaching others. Just ask!

Eat smart, ask questions, and always take care of the berry bushes. :)

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

Been playing since pretty much the beginning and I kinda wanna know how much time I have spend on this game.

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.

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...

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 ...

Tighten up your
riding laces.
Fear shall smear
across their faces.
Tarr pit north
one hundred paces.
Gallop off and
to the races.

Leave them t'wonder
where their face is.

Headless specter
nightly flies.
Deaf to all their
whimp'ring cries.
Shining treasure

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.
