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...

One of my favorite parts about this game is that every death is sudden. You know you're going to die at 60 minutes, you always will but it's still sudden. You still don't want it to happen.

This game is very fun! What you do with your life will affect future generations, they get to build off of what you create.
I'm the proud Eve of the Hawk fam, the 5th longest living family in the game!

Really boosts the experience. While the crafting thingy is still vague, it's better than the vanilla one. The zoom out feature also helps me search for stuff and not get lost.

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!

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. ...

Update: Town Launch
May 11, 2024


Launch pads must now be built in populated areas, with coordinates discovered from the remote orbital alignment location. This brings rocket-building home, returning it to to community endeavor that it was in the beginning, while still limiting rocket launches to once every five hours.

There have also been many fixes and improvements to the Editor, based on feedback from the Another Planet content team.

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.
