In the magical land of Equestria, two alicorn sisters raise the Sun and the Moon every day to give the world a night and day cycle, basic for the survival of life. There are also two alicorns who rule over two very core aspects of life and harmony itself. Those are Love and Friendship. While not as ancient as the two sisters, all princesses are essential to the world's balance.
This balance is also sustained by the hard-working ponies, who make the seasons change and manage the weather to fit their needs, so everypony has enough food and water, and every animal is also attended to assure that any of them are caught in the changes of seasons.
But what about the planet itself? What about Mother Nature?
This is the question that Gaia asks when she arrives to this foreign world. After so much work her son persuaded her to take a long vacation in Equestria, saying that she needed one and assuring her that he would be in charge now, and she must take a break. But what can a several billion-year old alicorn possibly do to pass her time in this land?

Looks good.
This is adorable! Thank you! You are a good writer! This story is cool!
5568034 Thank you
5568078 Glad you like it! I hope to keep delivering adorableness and awkward situations in next chapters
well i do say this is quite interesting and i love how you portray Gaia infront of everypony.
I'm pretty sure that as far as manners and propriety goes, Gaia is covered by the 'grandfather clause'. A being so old as to defy comprehension can only really live in the moment. What does she care for the opinions of others, when she doesn't even care for the opinions of her own children (beyond doing them favors when they beg)? She simply IS, like a mountain, like a planet.
I'm guessing the role of Mother Nature is split between all ponies (and counter balanced by Discord) in Equestria, as the ponies control the weather, growths, and magic outside of the chaotic Everfree.
This story is adorable, please continue it.
Are you making one chapter a day or do you already have them written?
Either way I really like this one. Leaving the translator behind gives so much room for comedy value and for them to really see who she is, to an extant.
Keep going your doing great.
And I just read up on what simearth was. I wonder why no one has thought of this type of thing before?
It someone has then I haven't seen it.
Either way I love the fact that Gaia is the "player". You always seem to come up with great ideas.
What year is it for her "ingame"?
...Wow. Just when I thought MLP had been crossed over with everything. Never would have thought of this. I must read it. :)
5568522 Glad that you like the story and the character
5568643 You are correct there, she goes with the flow wherever it goes and doesn't really care for anything except life itself. She likes the lands flourishing with fauna and flora and with that she is happy. She has suffered enough loss when she was a foal. Being barely a filly and have to endure the loss of millions of creatures that are essentially her sons it's a tough pill to swallow. She had a lot of time to work on that after all.
I didn't thought of that right now but yeah, nature in Equestria will be probably an orphaned child being cared by anyone who paid enough attention to it, being mainly cared by the own inhabitants of the planet like the ponies. A completly stationary planet can't generate by itself any kind of seasonal change since solar radiation is uniformly distributed through the surface.
I'll try to conitnue the story and the adorableness. Thank you for your comment
5569109 Since I want this story to be a excercise in being constant (which is a bit hard to me at the moment) I'm writing them day by day. The first chapter was resting on a file like a year but I decided to rework it and finally put the story for the public.
And yes, without magical or technological translator the development between the characters can be more funny and natural
About the idea of doing something like this... probably it's a bit hard to come with this kind of mix. I mean you got pretty well the concept from just googling about the game, it's just that the game is so obscure and unknown that anyone here probably doesn't know about its existence.
I try to always do something, if not completly, a bit new to make path for ideas that were never taken into consdieration before. I hope to keep the quality to back that initial boldness that made this story possible
The year in game, as well as her age, is 4.281.006.479 years. Full exodus of a trichordate civilization. I have noted all of the events that happened during the game. So yeah I can point wars; asteroids, tidal waves... anything. It gives me quite the material to work on her backstory
Ultron approves.
AWESOME!
IT NEEDS UPDATES!
Fun story (waiting for the next chapter
)
Just a detail but, I thing you don't use enough commas
(Some sentences are too long to be pronounced without a breath 
)
Quite a lovely story. It is quite enjoyable!
5569248 She seems to enjoy being a mother to much to allow anything overly bad to happen to her species, but if they start to fight I don't know if she would let them or put her hoof down. And there is the possibility of there being more then one sentient race from her world. Could there be a malicious force waiting for the chance to strike while she has a vacation!?
Either way, if you let me I can help edit the stories if you wish. Just get rid of the minor spelling and grammar errors through out. There aren't to many but they are very much there.
Oh well, even with them it is a good story.
IT NEEDS MORE!
5568405 IT NEEDS MORE!
Gee thanks random anon for putting a dislike. I would like to know why you disliked it though but you can't win them all... If you change your mind you know where I am. Probably it was a troll that thought that it was funny to put a dislike since someone put the story on a group called "No Dislikes Group". You can be all silly and stuff but... really, anon?
5569189 The best crossovers are the unexpected ones
I hope the story is of your liking 
5569286 Glad to count with the approval of Ultron
5569353 I'm working on it, but I'll wait until tomorrow to make the chapter public. By tomorrow mean a few hours from now don't worry
. Also glad you like the story! 
5569357 You are probably right. My first language is spanish and it's a bit hard to see where I make mistakes. Still this is just proofreaded by myself right now
5569358 While a bit paradoxical, I'm glad that Gaia likes a story about... Gaia
5569360 Yeah she tries to avoid conflict whenever she can but wars are unavoidable. She can only influence on a global scale through her son, who is the one who controls how the civilization develops on her planet.
Also those are pretty good plot drives but for the moment it will be just Gaia being herself and trying to relax.
5569372 I'm working on it. Gee I'm glad you liked it but I need a bit of time
5569417 If you need an editor I can help.
5569421 Ready as well, SIR!!! gamesprays.com/files/resource_media/preview/pinkie-pie-salute-6050_preview.png
This story is great!
5569421 5569464 Thank you both for offering to help me with this. I would like to try and publish the chapters as I'm doing right now to try and improve a bit (and to write and publish every day on this story), but it would be a great help if you spot bad grammar or spelling. You can send me via PM what you think that needs to be corrected and then I'll make the necesary editions on the story. Again, thank you both for the offer
5569465 Glad you like it!
UPDATE?!?!?!? please...?
5569503 Fimfiction.net has a password setting for viewing past stories. You input the code and send us a link to an unpublished chapter and we put in the code. That way we can edit.
5569464 PM the author.
Why were they alicorns? I might need an explanation...
5569528 Ah true, I forgot there was such a feature in the story system. I've been away from the writing far too much time it seems
. 
Anyway, I don't want to impose so don't worry too much about it. While I would like it to be as free of mistakes as possible I also want to publish one chapter per day so it can be a little inconvenient for the process because maybe you are not online when I want to publish them. Again, don't worry too much. We can edit and change anyting along the ride
5569504 Working on it!
5569536 Just a silly and simple association. Canon Equestria pretty much has living embodiments of primal forces in pony form, so why not other places too? It's like the thing that happens with Star Trek, in which almost every alien is like a human but blue; gree, with scales, etc... Plus Gaia packed in pony form is way more cute than just a globe with eyes and mouth, right?
5569557 I'll try to help. But I'm happy you're attempting a daily update!
5569570 In the Star Trek-verse, it was explained in ST:TNG by a bajillion-year old extinct race seeding the primordial soups with their genetic sequences.
"Prometheus" totally stole the concept and made it stupidly grim-dark to tie in with "Alien".
Laaaaaaaaame!
Oh, and the Marvel-verse is basically just different-colored humans too. Same difference.
I'm confused... Who is Gaia's son? Is it one of the Titans or Giants, or did you just make it up?
Have Gaia make Celestia and Luna feel small and inferior without even trying or being hostile. Bonus points for you if Discord gets the same treatment.
this is great!
She's going to out motherly celestia, isn't she?
Bonus points if she sends Discord to timeout. 
5569531 I feel like i see you everywhere...
5569668 Well, there goes that theory. Still, it's pretty romantic to think about natural parallel evolution, right?
5569754 Gaia's son it's not really relevant right now, but he is a smaller alicorn and he basically commands the evolution of the civilization that flourished on her planet.
5569778 5569965 She isn't trying to make others smaller... She just mothers every creature since, at least on her world, she is their mother.
. Whe shall see about Discord in the next chapters 
5569895 Glad you like it!
"Well girls! The princesses are already informed and..." Twilight said while walking outside, Spike sitting on her back. She was left speechless because of the bizarre scene.

5570052 Thanks for spotting that. Fixed!
Faust help the ponies if Gaia get bored.
I eagerly await more.
I wonder when Twilight or Celestia will pull out some sort of translation spell.
P.s did you do the art? Love the design.
Quadrupeds. That's the word for four legged beasts.
5570101 Lucky for them that Gaia is easily pleased and enjoys simple things
They will try magic that's for sure, but... well, you will see.
And yep, I did the art! Glad you like it!
5570107 Whoops! Thanks for spotting that. Fixed!
5570046 Like bats, birds, and bugs... all independently evolved flight.
But honestly, we may find that cephalization (a compact central nervous system, which is far more efficient and complex than a dissociated one) and articulated appendages are exceedingly common among advanced species in the long run (fingers make it so much easier to develop and utilize tools and machines).
So creatures with very finger-like front feet like rats could one day learn ninja skills and raccoons could be abducted by aliens and surgically altered and then hang around with a talking tree that has a very limited vocabulary!
5570149 Her design is really novel, both elegant and wild.
Do you have a tumblr or a devaintart I could stalk?
what the fuck is this shit you have no right to have such adorableness I demand you take it down because it is ruining my sour mode im smiling and stuff! rude!
*pulls a Applebloom*
I need the next chapter and I need it nooooowwww!!!!!
Erm, some of yer words ran away.
(Not just in this chapter)
You had my curiosity, and now you've caught my attention.
this is a really nice cozy story
Apparently, Equestria is a good vacation destination.
I was going to point out a need for an editor, but it seems you've found a couple, if the comments are anything to judge by.
Loving the story, it's whimsical and amusing to me. Keep it up, if you will!
Congrats on getting featured.
So can we expect more?
Had to google simearth, but this looks fun.
Only saw one error with sentence structure....
But by Celestia's flank I love this story!!!
Man, I haven't played Sim Earth in YEARS.
This story has made me want to play it again.
