Yes, but even though its a "worm'     its not biological.  The could/should be more susceptible to info warfare

Yeah, either WMD could be considered some type of cyber attack, but of course we aren't trying to be realistic here.  We need balance.  If Yor needs a buff, sure, maybe they would do that.

On that note, Tidal Waves should have double effect against Yor, as Robots can't swim and they rust.  Are you willing to accept that?

I take it you've never heard of this.

Your right never had.  OK I give, as was said perfect biological weapon against robots.  Except, as stated in artificial,.. ~victory in 15 to 20 years,

Total denial. I am not attributing that as a cause to not make synthetics immune to biological warfare. They are not biological. Period. For immersion and STRATEGY sake this must become reality. This must be in the game it's to perfect to pass. This change is needed!

Also, synthetic creatures SHOULD NOT want snuggler colonies.    

I'm sure Yor aren't made from simple metal but alloys which don't rust, otherwise they couldn't go outside during rain, and also an atmosphere may hold water anyway that will corrode them over time.

And because they don't need to breath and can withstand pressure much better than carbonbased landlifeforms they shouldn't have difficulty surviving Tital Waves, just like Data in ST they sink to the ground and walk back to land. Guess they don't have openlaid circuits or cables as well, because, as have been said, this would be detrimental for them during rain.

As for bacterias, that's what maintenance is for. I think they can use anti-organic cleaners of severe magnitude, like bathing in benzole, stuff that organics could never possibly touch because of the danger it imposes.

I guess the devs would have to decide if they want to have invasion tactics work differently for different races.

All the conjecturing to argue against existing game mechanics is fun but not necessarily relevant. You can explain ANY game mechanic with enough imagination.

Biological warfare uses weaponized versions of the bacteria/virus/fungi/toxin that accelerate corrosion. This is not a slow process. Yor are made with metals that can rust or be degraded in some fashion. Therefore biological warfare is justified as usable against synthetics too.

There. See how easy that was?

Completely unrealistic? Are you saying that it is has to be something in existence today for it to be realistic??? There also is not a single antimatter torpedo in existence today, would you suggest that be removed from the game too?  And no Zero G Arenas that I know of either. Not sure how far the government is into developing the Doom Ray, but I'm pretty sure we are at least several years away from that being realistic too. Etc etc etc.

It would be cool, but it doesn't exactly take a lot of imagination to explain why they don't. There's really no reason why the Yor should be immune to genetically tailored biological weaponry. The biological weapons in question aren't blankets laden with smallpox; they're highly developed, lab-constructed, weaponized micro-organisms. Merely by accepting the concept of the Yor in the first place, we tacitly accept that silicon-based artificial life is possible in GC lore, so why can the Yor be built but no no other silicon-based lifeform?

While non-ferrous metals don't rust, they're usually still reactive with other elements; it would be fairly trivial even today to engineer a self-replicating, highly infectious lifeform which attacks certain specific elements and thus causes the Yor to break down catastrophically. Should that be made into a separate tech line ('silicon-based bacteria')? Maybe, but tbh I think there's bigger issues to deal with right now.

Irrelevant. If you are genetically modifying the organism, you can specialize it to the point where it attacks metal preferentially. We're working on a nano-scale at this point. 'Organic' is just carbon compared to silicon at the scale we're looking at. IF you insist that biologicals must be organic (which they really don't, as it's arguable just how alive some micro-orgnisms are - prions, for example, are basically just lumps of protein), then we already have examples of naturally-occurring, unmanipulated bacteria which eat metals quoted within the thread. There's no reason whatsoever that couldn't be weaponized, accelerated and adapted, even with present-day GE technology. And if we include nanobots into the biological category (as many nano-bots are basically constructed from biological materials), then a very fast-acting, silicon-based, self-replicating grey-goo machine would be able to reduce the population of whole planets to dust in a matter of hours, before the Yor have a chance to quickly refit themselves.

No, that's how we see it too - it's just that this isn't actually that different to organics. Just as the Yor might adapt to make themselves immune to the latest anti-robotic biological organism, we immunize and vaccinate. I'd assume that the 'biological weapons' in question are in constant development, as are defences against them; the initial tech cost is the basic research needed to create and tailor a wide range of offensive weaponized biological agents more or less at will with next to no cost - the computer to manipulate the genome, rather than the manipulation process itself.

Firewalls aren't impervious, and even heuristic anti-virus software needs to be updated regularly. Once again, as long as the Yor are aware of a particular computer-type attack then they will undoubtedly move to counter it, just as the squishier races presumably feel the need to produce anti-toxins and targeted antibiotics in response to new biological attack vectors. I expect that the Yor do have some means to isolate or shut down whole areas of their network that are infected with APTs; indeed, personality-wise, the Yor response to an aggressive, fast-spreading computerized assault on their primary operating systems is probably just remorselessly isolating and kill all units which have contracted it rather than saving them in some way. That may be entire planetary populations burning their modems and waiting for death.

But galaxy generation simply implies a massively higher level of control over the laws of physics than we presently command. Galaxies generate over time. Therefore, the rules to create galaxies exist in physics. So we just need to know how to accelerate the process. If gravity generation can be achieved, then it can be done on a massive scale (eventually), which means that you can collect the matter rapidly into one place. Then you just ignite a few pockets of hydrogen to make some suns (rather than waiting for them to do so themselves), and the whole process goes by itself from there - though obviously you can continue to adjust by that point, using field manipulation to shunt vast quantities of atoms together and subjecting them to pressure until they form planets etc. None of this is outlandish fantasy stuff.

By the end game, you are on the edge of transcending physical reality completely and reaching a higher state of consciousness. You're operating in 11 dimensions. Bending the laws of physics should be fairly trivial at the remove. Moreover, the fundamental particle which we play around with presently are a distant memory; science has moved on and there's been paradigm shift after paradigm shift. The cutting edge of the Standard Model is a quaint artifact of history at that stage, like Pholgiston or Ether; quantum physics and relativity have long since settled their differences and been replaced with the Theory of Everything. 'Doom Ray' is as good a description as any, since frankly we have no idea what the physicists of 2400AD will be talking about - but we can be pretty sure it won't be quarks and M-branes. Half the comedy of the research screen descriptions comes from the fact that these are insanely highly-trained scientists trying to explain what their working on to someone who knows so little science from their point of view that you don't even know the name of the forces that they're manipulating. It would be like trying to discuss the workings of an atom bomb to a medieval peasant. 

Part of playing a future sci-fi game is the willing suspension of disbelief. You have to accept that in the future, we are going to be able to do things we don't think are possible today. There are some really good WWII simulators out there if you don't want to accept the possibility of future technologies being beyond what you consider realistic.
