TBT: SimEarth

I’ve been on a video game kick lately, diving back into the Civilization games and listening to a lot of the Gaming Historian on YouTube.  As such, it seemed like a good time to look back at another video game post, one about the planet simulator SimEarth.

SimEarth was one of those games that I found instantly appealing—a massive simulator of an entire planet, going through all its geological, biological, and civilizational phases.  Even growing up in a household that rejected the theory of Darwinian evolution (a theory I still don’t accept, although I acknowledge that adaptation and mutation are both possible and happen frequently), the prevailing scientific understanding of our world made for a fun video game.

The possibilities were endless.  Want to be a Deistic god and let the world run on its own?  Go for it.  Want to interfere frequently in your planet’s development?  Do it!  Want to make starfish or Venus fly traps sentient beings capable of forging an advanced civilization?  Why not!

I used to be able to make pretty compelling planets in this game, with rich histories and multiple species in succession rising to sentience, before heading off an intergalactic journey of the stars.  Apparently, I lost any skills I had, as my last game a couple of years ago (detailed below) ended in nuclear winter.  Oops.

With that, here is 27 May 2020’s “SimEarth“:

Yesterday I wrote about SimRefinery, the oil refinery software lost to time (I’m praying it’s sitting on a long-forgotten floppy disk somewhere).  What I didn’t tell you was that I had succumbed to a mild but annoying stomach virus, so I was essentially useless for the rest of the day.

Of course, what better way to spend one’s time when sick than with video games?  After writing about SimEarth and doing some nostalgic reading about the world-building simulator, I tracked down a playable DOS version.  A helpful commenter also linked to the game’s 200-plus-page manual, which is necessary for accessing the game.  Anyone familiar with 1990s-era computer technology will recall that, in order to prevent piracy, games would often ask users to look up some piece of information buried in the manual, the theory being that if you owned the game legally, you’d have the manual.

During this sickly walk down memory lane, I realized how much I had forgotten about SimEarth.  The game is more complicated than I remember.  It’s not that deep, but what makes it difficult is balancing all the different inputs to your planet—the amount of sunlight, how much of that sunlight is reflected by the clouds and the surface, how much cloud cover to have, how quickly animals mutate and reproduce, how frequently meteors strike the surface, etc., etc.

It seemed that, as a kid, I knew pretty much what I was doing—if I wanted to turn the planet into an icebox or a veritable Tatooine, I could do so without too much difficulty.  But I also knew how to create a thriving, biodiverse planet that could nurture intelligent life.

Not this time.  My planet, Bootanius VIII, really struggled to develop life more complex than radiates (jellyfish and the like) and some simple bacteria.  This screenshot is about as biodiverse as my planet got:


After tiring of waiting for more complex life-forms to develop organically, I plopped some insects down in a forest.  That quickly resulted in the development of carniferns, one of the fun “Easter Egg” animal families in SimEarth.  Essentially, carniferns are Venus Fly Traps, and SimEarth makes it possible for them to gain sentience and start a civilization.  So I used the Monolith option—essentially extraterrestrial interference—to grant the humble carniferns intelligence.

Eventually—and I’m talking after hours of leaving the simulation to run itself while I worked on finalizing grades—the Stone Age carniferns moved through the Bronze and Iron Ages, finally achieving industrialization, then the Atomic Age.  All was going well until their supply of atomic energy began to run low, at which point a massive atomic war engulfed the planet in nuclear winter!

I cut off access to atomic energy and the war ended, with radiation lingering for millennia.  Growing tired of my warlike Fly Traps, I used the monolith again to hasten them along to the next phase:  interstellar travel.  SimEarth has every city launch from the planet, thereby returning the planet to the animals, giving another species a chance to rise.

After that, I sincerely tried to relearn the terraforming mechanics to make a world that could sustain life.  But after my seas were overrun with single-celled bric-a-brac and my Stone Age dinosaurs collapsed, I decided to call it a night.  Clearly I’m not cut out to manage an entire planet.

A big part of the appeal of a game like SimEarth is the stories.  Want to create a desert world populated by lizard people?  It’s possible (I did it, years ago).  Want to design a world inhabited by civilization-building octopuses?  You can do that, too.  Indeed, you can just let the simulation run and see what happens—will oceans develop without your interference?  How quickly will bugs show up?  What happens if I change the planet’s axial tilt a bit?

I’m looking forward to starting fresh with another planet soon.  Maybe this time I’ll get the delicate balance right, and all manner of critters will o’er flow the surface of the globe.

Or it’ll be another nuclear winter.  D’oh!

  1. Check back here tomorrow, Tyler. I’m in bed today, giving my ailing back a little time to recover and I’m not a huge fan of posting on the tablet; predictive text keeps changing every damn word! 😂

    Later dude.

  2. Thank the Lord, I can post again! My back, by the way, is still a little tight but as long as I continue bathing it and smothering myself in Deep Freeze, I’ll be fine. I think! 🙂

    These sorts of games are going to be played by the type who bought and played these when they came out. You’re never going to get your new gamer into them for a ton of reasons; mainly the graphics but the fact that there are many games about that do the same thing but easier on the eye and much more expansive. I like that you can still play these games, if you still have the old systems and disks to match. Yes, I remember floppy disks. I even remember the tapes for the Spectrums and Commodores. Boy, weren’t they a pain!

    If you’re one of the rare breed who look at this type of game and want to play it, you could still buy the retro machines that hold them. Problem is, they’ll probably cost a lot. My brother still has the old SNES, he might still have our old Megadrive but not many will have the very old systems with working games. That said, I reckon you can get patches for Sim games that might not be a pain to install on your PC. They’ll be slow going though and they definitely won’t hold your hand, which I think is awesome.

    I’m glad you’re enjoying it but you might want to get some more land onto your expansive oceans. A bit treacherous there, mate! 🙂

    • Praise the Lord! It’s amazing how a bad back can be so incapacitating, even sitting at a computer to write can be a chore.

      I found this free (and, I presume, perfectly legal) version of SimEarth here: https://archive.org/details/msdos_SimEarth_-_The_Living_Planet_1990

      In those days, many games had special password protections to prevent piracy. So with SimEarth, the manual of which—which contains the passwords for the game—can be found here: https://www.freegameempire.com/games/SimEarth/manual

      This DOSBox emulator version is the one I was playing, and it was not difficult to get running at all.

      There is a version of for the Super Nintendo, though I have never played that. My younger brother is currently in possession of the SNES, which both of my brothers and I pitched in for to purchase in the early 1990s. It is still kicking now; my niece and nephews sometimes play it.

      With DOSBox, you can emulate tons of those old DOS games, many of which are now abandonware and available legally for free online. Good Old Games also sells many of these games, complete with DOSBox emulation built in, though some require some tinkering to get running properly. That’s made ultra-retro gaming much more accessible to everyday gamers.

      That said, you are right—these old games did NOT hold your hands. Like I wrote, this bad boy came with 200+ page manual. I remember devouring the very thick _Civilization II_ manual the year I received the game for Christmas. For me, that was part of the fun! But, as I noted in the post, I have lost much of my SimEarth abilities. D’oh!
