Species: Nerada

#1 Post by Jaumito » Sun May 20, 2018 6:45 pm

(Sorry for not following the proposed guidelines for new species here, the reason being this one is already near-complete and all the blurb can be found in the Encyclopedia.)

Status: working, but needs some more tweaking and polishing.

Reason for leaving er, existing: pick the two most (in my opinion, at least) crippling traits a species can have and still make them viable. Specifically, that means NO_RESEARCH and NO_OFFENSE_TROOPS. This won't change, ever, since it's the whole point of the species. Anything else is up for debate.

How it all started: as three different species, really - but it's only when I merged them recently that I thought I was on something interesting (i.e., a different enough playing experience.) For the record, the inspiration for these species were -
  • The Vashta Nerada (from the Doctor Who series) - that's where the Nerada got their name from (obviously!), plus the Scototrophic metabolism and stealthiness (I dropped stealthiness at the moment but may reintroduce it later, just for thematic reasons.)
  • The planet-creature from Stanislaw Lem's novel, Solaris - not much left of it except the inability to communicate with other species (in game terms, to 'invade'.)
  • The Alternate Reality PRT from the old Stars! game - a remote-mining race living in orbit (here, it means on asteroids), thus the Kilandow-like bonus.
Note on the Scototrophy metabolism:
(It should be skototrophy, actually, just like in skototropism - but since it's a neologism, I claim ownership on the term and I like this spelling better, so...)

About the implementation: I have no idea how to write a true new metabolism in FOCS, so I just reused the "light sensitive" code from the Banforo. It's a hack but it works transparently enough, except the metabolism won't show in the Census menu.

So basically it's Phototrophy in reverse, although not exactly a mirror image. The numbers aren't arbitrary, the math guys here will probably notice there's a Fibonacci sequence lurking in the progression. In my experience so far, I think it's slightly worse than Phototrophy but that's OK, I believe that metabolisms don't have to be strictly balanced as long as the playable species are.

About the species itself:

You'll notice there are two 'good' environments. I wanted to make Barren planets adequate only, but it had an annoying side effect: you could then terraform your planets but it wouldn't actually do anything. So until this is fixed, enjoy the better habitability.

Nerada normally start on an asteroid field, and their sun is set to 'orange' if generated as yellow or brighter. You'll notice sometimes you don't get full production on the homeworld when this happens (well, I think the loss of production is related to the sun's reset although I have no hard evidence for that), but I don't know how to fix that yet.

It doesn't show in the species' description, but Nerada build colonies one fifth as fast as standard species (0.8 multiplier.)

Communal vision is there for a reason: the AI sucks at handling Nerada, so you can start a new game if you don't want to play against Nerada AI.

SP_NERADA_DESC
'''Description:
The Nerada look like tiny amoebas made of pure darkness, which form planet-spanning colonies. While individually they are barely sentient, the colonies themselves have a form of telepathic intelligence capable of communication with similar lifeforms across interstellar space. When they land on a new world, they start to multiply dazzingly fast. Their ubiquitous presence, and lack of both a central decision organ and a command structure, make them very hard to dislodge from places they inhabit. However, their inability to properly understand other lifeforms make them unable to invade previously inhabited worlds. Since they're unaffected by gravity (or the lack of) and don't need to breathe, they can thrive on asteroids belts that look like the barren wastelands they favor most.

Social Structure:
Strictly speaking, the Nerada don't really have one, since usually there's at most one Nerada colony per planet. They're more akin to the cells of a multicellular being than to ants or bees. They don't really understand the concept of scientific research, yet they're very industrious - sometimes through the mind-controlled bodies of larger species, but they can also form 'bodies' of their own when they need one.

Awesome work.

They remind me of the "monster" of one of Dean R. Kontz books that I read when child. It was a huge, single-mind, distributed "organism" with a composition related to petroleum that could separate parts of it and mimic other organisms/animals shapes (although in black, IIRC) and capabilities. It lived deep in the ground, getting out every few centuries to eat anything that moves. It could sense others thoughts and memories, and use it against the victims, and was very intelligent, but didn't have feelings and the such and could not really communicate to the other beings (that in any case are just prey).

A suggestion:
The Nerada could justify its good defense troops and absent offensive troops by chemical/environmental stuff: they naturally (and unconsciously) produce many kind of toxic agents (to which they are immune) to keep their environment free of foreign organisms. Those agents are not just some "venom in the air", they include chemical and mechanical (like explosive spores) stuff that can break appart armor plate and be a challenge for invading mobile troops. But appart from that, they have no real means to exert violence on other beings, and this defensive environment can only be built up with time and effort (which renders it useless for invasion, since natives will wipe out the pest/infection that the Nerada seem to be).
In some sense, the Nerada, made of darkness, full of "hate" to the light, and which will always kill anything that tries to cohabit with them, could be seen as "evil".

An idea inspired on Nerada: an ultimate-research, no-industry, phototropic, no-offensive-troops, communal vision, asteroid-dwelling species to be the "bright" counterpart/nemesis of the Nerada. Good or great planetary stealth, or great planetary defenses (if that exists), probably needed.

That's actually close to what was in the first draft but I eventually ditched it as unnecessary. Think about it: how do you fight what's basically a huge mass of goo that's everywhere and without a central brain or a command structure you could target? That alone would make them the ultimate defenders. Similarly, the lack of offensive power is due to the need to achieve critical mass to fight (or actually do anything) effectively, and to achieve that critical mass, the Nerada have to grow peacefully on an uncontested planet for a few turns. You just can't squeeze enough of this "Nerada goo" into troop transport ships and expect them to be sentient enough to grok concepts like strategy and tactics on arrival.

A good analogy would be the way gravity works: at large scales it's the most potent force in the universe, but it peters out to nothing if you haven't trillions of tons of mass at hand. Nerada intelligence is basically a function of their mass.

No industry - it didn't even cross my mind. Probably because there's no counterpart to DTC for industry. Could be fun, I'll have to try that.

A few tips for playing the Nerada:

1. Stop reading NOW if you want to figure out all of this by yourself. Nerada are supposed to be a challenging species, why wouldn't you want to keep the challenge up?

2. ... but don't make the challenge harder by picking 'Young Galaxy' on your first try. You'll be punished for it. With extreme prejudice.

3. Use your superior industry to colonize aggressively. You want to milk Nascent Artificial Intelligence's flat bonus out of every world you can live (or survive) on - even if it's rated 0.25. Lots of crappy planets is better in the early game than a few fat and juicy ones. At least until you research Distributed Thought Computing (which should be an early priority by the way.)

4. You have bad supply and thanks to your abysmal research, that won't improve for a while, so consider outposting some uninhabitable tiny/small planets for the supply bonus. Again, great industry helps there.

5. Ancient ruins are more valuable to you than to anyone else, because extinct species. Kilandow are the real prize here.

6. In Neradenese, the sentence "There's no ancient ruins in sight" translates as a single word, and that word is "Exobot". Too obvious for a hint? Maybe. The real reason I'm talking about Exobots here is - don't forget to set them to research (as I do way too often.)

7. Avoid turtling. You can't conquer enemy empires early, but you have all the tools you need (good industry and weapons) to make their own expansion as miserable as possible. Don't let their better research overwhelm you.

8. Blue stars are your sworn enemy. They're lethal and will remain so the whole game, even when you've researched every growth tech there is. Just pretend they don't exist. By the way, you did read (2) above, right?

9. Planetary starlane drives are your friends. Especially if you ignored (2) above.

10. The Laenfa are heretics and the Chato an abomination. Exterminate them on sight. Exterminate everything that looks blue-ish on sight.
