Looks good to me. makes them harder to kill with a single ship but still vulnerable to a dedicated attack. The AI should assign them a priority in its attack logic, they also should cost more to build so once destroyed they cannot be replaced in one sigle turn. A progressive cost pegged to the current age would be nice.
I did increase cost, doubled it. I can see if there is a away to make the cost progressive. (I know I can tie it into tech but that is a clunky way of doing it)
On the diplomacy side, the changes you made may still be slightly overpowered. I planted the embassy on a class 26 bread basket planet and surrounded it by consulates and the missionary improvement. Population is now at 56. After researching up to the diplomatic district I now have a status of "dreamy" with everyone except the Romulans and Borg who are "captivated". I even have a great status with the minor races I am at war with.
Yeah I seen this too, hense the nerf I introduced to ID:- 3, 5, 7 and 0.2, 0.4, 0.6. It is 2, 5, 8 and 0.3, 0.5, 0.7 in current build. What level did you manage to get the Embassy upto? 12? Did you build Culture bases? And how many? I might nerf it a tad more:- 2, 4, 6 and 0.2, 0.3, 0.4. Still toying with it.
As an aside, the precursor defended anomalies are too strong on an abundant map I believe, getting several 25% boost to all production with 100 + planets is significant as well as the 2000 credits that come with it. It would be nice to have a setting just for them so the normal ones can be abundant but the precursor artifacts are rare. The AI also seems to ignore them which gives me a large advantage.
Also toying with removing the encounters from Anomalies purely because the AI ignores them, even when they have fleets capable of taking them with no losses. No idea why SD is making the AI ignore pirates its absurd.
