On the Cynetic thing, it is interesting but I would rather aim for simpler than that for now. Having the new resource antagonize the AI if you use it is theoretically ok, but there's a few too many "joints" in the proposed "limb"; or at least more than there seems to be any real
need for.
Complexity aside, I'm concerned that a direct AI response to your using the resource gets more into the "treadmill" feeling: obviously there has to be a counterbalance to everything, but if it's a "step on the rake, immediately get hit in the face" kind of counterbalance... well, that's not usually much fun. Kind of like how golems were a long time ago where bringing one to an AI planet would cause it to immediately spawn a ton of free ships there to offset your local advantage.
The growing-response-over-time thing would be less immediate, but the player's
perception (at least if they know the rules) is that they're immediately incurring a penalty.
All that said, I think I'd be in favor of something where a destroyed crystal mine would reset to usable-by-you after an hour or two,
but until it resets it increased AI wave/cpa/exo/etc size by 5% or whatever. But along with this rather than making the mapgen-seeded crystal source a capturable "mine" it would just be a neutral invincible thing that doesn't produce anything on its own but you can build a "crystal mine" within a certain distance of it. The destruction of that mine is what would trigger the temporary AI boost.
Anyway, somewhat more complex than I'd prefer, but perhaps with refinement it'd be worth it and would add a better counterbalance to the new opportunities.
My main concern with my proposal at the beginning of this thread, and some have mentioned it here, is that I don't see how it would avoid being a "capture one crystal source at low AIP, watch netflix until you hit the crystal cap, commence actual playing" situation. Even if there were a step-on-rake counterbalance to harvesting (which would be less than ideal anyway) it would just become a matter of computing the ideal quantity of netflix to apply
That leads me more in the direction of it being a "population" resource like energy where it's not harvested at all and thus can't be hoarded via netflix, or it being an "exhaustible" resource like knowledge where you can harvest it all pretty quickly but then it's gone... but I don't want to go either of those routes, as we already have resources that do those things. Making it energy-like would be tolerable to me, but I'm hoping there's a better way.
