Actually I think this is one of the strengths of the idea of making knowledge raiding more "lively": the AI should realize that the human's MAIN way of becoming more dangerous is through knowledge. Without knowledge you simply cannot get enough extra ship cap and higher mark ships to take down a suitably defended AI homeworld. Or at least, I'd be very surprised if someone could pull that off on, say, higher than 7 difficulty even with all the ARS-unlocks since you'd still only have mark I ships.
So in my opinion the AI should take a decided interest in denying you access to knowledge on planets you don't own.
This is exactly why I wanted to get at least a better mental handle on what knowledge is. That is, an actual resource that is quantifyable from the AI's perspective - such as hacking into their command center and downloading data) or passive scans of their ships / technology.
Depending on what it IS, I can think of several ways to make it more interesting and have it at least partially scale with AIP without needing to trigger some sort of terminal-like ship spawning.
WARNING -- the following would be a major re-tooling of how knowledge works in game now... however, the more I think about it, the more I like it.
Lets say that we declare 'knowledge' as the physical hacking into of ships databases and command center databases, and examining wreckage of AI craft.
Knowledge raids in systems you own would be:
- For each destroyed AI ship in the system you would get 0.1 units of knowledge up to a cap per AI ship type seen in game.
- For the AI command center / warp gate / other capturables there would be a fixed value for pawing through the wreckage as well.
Research stations would travel around 'examining' this wreckage as a passive means of generating knowledge. However due to the cap per ship type, this only gets you so far unless the AI gets a new ship type through AIP increases. In order to really get AIP you'd also have to try to get live data:
K-raids in enemy systems would be to try to get your research stations near live enemy ships. research stations would get a type of 'beam' weapon similar to repair / tachyon beams. You'd either bring your research stations in under cover of a fleet and try to get in combat intelligence, or under a cloak, and try to sneak the intelligence that way. "Hacking" enemy ships gets you 0.5 units per enemy ship type, and some suitable multiplyer for sneaking your research stations near the AI command station.
This would obviously get much more difficult to do the more enemy ships are swarming around (increased AIP and planet Mk level), and you could easily make it harder to sneak the research station close to key enemy structures by placing more tachyon turrets around at higher AIP and giving the AI more of a reason to attack the research station for the fleet escorted research stations. After all, they're actually breaking into enemy data systems.
If thats not how knowledge works, I'm sure that the community could come up with other ideas (though I like mine hehe).
