I could tell you about how I repeated the process from before, placing the seedlings of my plant and animal categories on a newly created planet, but...nah.
Suffice to say I tried adding several planets to a single sun, but...yes, fortunately I let it go on a test run for about a billion years - fast forward, obviously - because those types of planets influence each other a lot if they're close and one day everything goes BAM!
I'd hate for that to happen on my next world. I admit, I gave up on the idea of several planets in the green zone. But!!! What did work was a strange construction of three planes that go around each other on a complicated path while at the same time making their way around the sun.
It admittedly gives me an intresting weather with regular ice ages and no regular seasons I can see, but...that just makes the whole thing more fun!
Anyway, where was I?
Oh yes, I planted loads of seeds on those three planets and then just let them run for a good, long while. Like, a couple billion years, without my interference.
What I got were these three:
Planet: Skybridge
The largest of the triplet planets, consisting of 60% Water, 26% Desert, 10% Green Coastregions, 4% Oasis
Temerature: Day: on average 37°C, Nighttime: on average -20°C
Seasons: no clearly defined seasons, tends to have irregular rainy and dry seasons
Plants (surface): two general types, one which grows and bears fruit or seeds during rainy times while staying dormand as a seed in dry times. This type also appears around the coasts and in most Oasis (how do you write Oasis plural????). The second type resembles cacti and can be found almost anywhere.
Plants (water): Abundant species can be found in nearly any water source. The types number in the billions.
Support creative writers by reading their stories on Royal Road, not stolen versions.
Other life: All animal types evolved from one kind of water organism. Pure land animals do not exist, although several kinds are capable of surviving on the surface for several weeks by digging into the sand during the night. However heat stroke is a danger during the day. Many Insects are capable of surviving in moist sand or as parasites in cacti indefinitely.
By the way, by the time I noticed I forgot about salt in the sea and things like, oh, iron or jewels in the earth it was kind of too late. But hey, I'm god here! So, well, now there are trees with nuts made of gold and such things, too...Tehee...
Money does grow on trees in those worlds.
The other two were one with 80% Water - It was the smallest and had lots of vulcanoes, but also very lively islands everywhere! It was kind of like loads of tiny rain forests and there was life everywhere! - and one that resembled our earth a bit...but the seasons were a complete mess. Ice ages followed by eternal summer that turned everything into desert and everything in between without sense or reason. Plants still survived there somehow, but animals tended to either spread explosively or die off because I set the reproduction and mutation rates really high there. Life there died off several times before I got it high enough - and allowed them enough power... Now it's a world of little dragons and firebirds that mostly survive on magic.
Oh, yes - I made an energy that's produced by tiny plant organisms in the atmosphere as a waste product and called it magic! The energy is a bit like electricity and the animals would be computers. Built from matter and run by magic. Honestly, with modern computers and what they can do...that's basically all magic to me anyways.
Just look at this Hacker dude's game!
