DarkSpartan explained some of the stuff I mentioned in the previous post. It's pretty hard to debate on anything... I think DarkSpartan decided on most of this before I showed up.
It's not enough to leap across the galaxy in an instant - perhaps it can only jump so far at a time, or long distances require an exponentially larger amount of fuel?
When earth is attacked, some of the alien ships are lost. We're able to figure out FTL travel by salvaging and studying the alien technology. This is a new theme - to me, at least. If it's been done, I haven't heard of it.
We really need a name for them, and the most immediately obvious one is the name we don't have a purpose for - "Trillek" - but I'll keep calling them "aliens" for now, just in case you don't like that idea.
Not answered, so I'm just going to call them "Trillek".
Somehow they know exactly where our home planet is, as they send in a strike team and nuke Earth specifically, rather than just nuking the colonies that have pushed too far.
Not explained how they know where our home planet is yet, but earth IS going to be the ONLY planet humans are living on up until the strike, in DarkSpartan's version.
After a brief war, the aliens develop a viral technology strong enough to destroy humanity's computers over the Internet - how, I have no idea, as viruses don't typically target hardware.
DarkSpartan calls it "The Reversal" - and I'm still not sure how viruses can destroy hardware.
At this point, the aliens are able to invade and take over human territory with relative ease, and humanity somehow manages to escape our alien overlords.
Still not explained how we get away with escaping after everything is wiped. It could be a one-off thing, and the aliens just write a virus to toy with us, but really, I think a sentient race would have some purpose in what they do beyond toying with another sentient species.
[Recolonization is] met with minor resistance from the aliens, who don't seem quite as keen as before on keeping us away.
Still not explained... I think that if they nuked our planet, then tried to send us into barbarism, they would try a little harder to defeat us the next time around.
The technological development having been massively impeded by some undefined force.
Given that humans had access to the knowledge to create complex computers, it would make sense that somebody, somewhere, would have the knowledge in their heads of how to create new ones... I can see the equipment used to create the computers getting destroyed, but not the minds of the people who created those. still not explained in entirety.
There's also the issue of how all computers get destroyed all at once, despite them being many light years away from each other, and that no virus could possibly travel faster than the speed of light.
More from DarkSpartan:
Edited about the above: Earth has no colonies before the Trillek invasion - only Earth. When Earth is attacked through biological warfare, whatever the Trillek do causes the environment to decay slowly, gradually making Earth a living (or dying, in this case) Hell. Earth fights back during the attack, of course, and manages to knock one or more Trillek ships out of the sky, which they salvage and use to research FTL travel in an astonishing ten to twenty years, at the same time building starships to evacuate as much of Earth's 10-20 billions as possible. These colony ships hold humans stacked like sardines in cryostasis pods, necessary to reserve space, and each of them is capable of interstellar travel. They reach their destinations quickly, and humanity founds a small interstellar empire from these new colonists. In the meantime, Earth decays, and many billions of lives are lost. But that's okay! :D In the course of 150 years (still seems pretty short), we're able to create a much larger interstellar empire. Maybe we just spread our population really thin, I don't know - but that's when "The Reversal" takes place and our computer tech is destroyed.
Zardoz - I'll get to yours soon (may have to add it onto this post) - I have to log off for now.
EDITED FOR ZARDOZ:
"Warp" is a value that varies widely depending on who you talk to, and which Star Trek series you're talking about. I think I went with The Next Generation values, which was personal preference - I preferred that series over the original.
As to a human galactic empire falling, yes, it's been used many times, and I'm personally more for the idea that humans have only managed to occupy perhaps a sixteenth of the galaxy. Even this would be an astronomically large amount to deal with.
As to the AI rebellion war, I really like that idea too - so long as we're the ones trying to break free of the AI. Otherwise, it's just been done too many times. In The Matrix, you have humanity trying to take Earth back, and the same in Terminator. You never have them actually fleeing Earth, though.
I'm still really, really, really for a good quantity of different randomly generated factions ingame - that way there could be some kind of dynamic diplomatic system. You could forge alliances with different star clusters, and wage war on others... Some might accept new visitors, and others might shut new visitors out completely, or offer passage in return for something. Maybe some might even try to charge a toll or something, or maybe a "visitation fee". Frankly, without a centralized, unified government, I think that humanity would fall apart and fight among itself, rather than hold hands and sing Kumbaya, or some interstellar version of "I'd Like To Buy The World A Coke". I also really love the idea of ruined space stations and dead colonies.
