making governments scale with map sizes?

One other thing you may want to consider evaluating for version 3.5 or later is the AI's use of the specialty ships one receives when changing to certain forms of government. Right now the AI is almost always scouting with these ships instead of placing them in a planet's orbit to gain the benefits associated with the ship (s). I would imagine it shouldn't be too hard to make a simple change to hard code the government specialty ships to always be stationed in orbit around the capital planet. Ideally, the specialty ships would be stationed at the planet with the most appropriate benefits, but if that is too difficult for the AI to figure out, an easy compromise is to just hard code instructions for the ships to dock at the capital planet. The capital will likely be the best place for most government specialty ships anyway. Thanks for your consideration. 

Shamelessly reposted from the 3.04 thread:

Can you please put in some code that destroys all (or all but 1) existing pop when a planet is conquered by an incompatible civ?

I would define "compatible" as Carbon/Aquatic with Carbon/Aquatic.   Synthetic only with Synthetic,  and Silica only with Silica.

It is slightly rediculous,  immersion breaking,  and game-breaking that a race that spends so much time and resource to build more pop gets unlimited instant free pop conversion if they take over a meat planet.    It is only slightly less rediculous (but more amusing) that when a meat race takes over a synthetic planet,  the robots all start having babies.

One other thing I think is very silly is that conquering a planet that has an Capital City keeps the Capital City.   This is also nonsensical - if I can have multiple Capitals,  why not just build them everywhere?    I think any conquered Capital City should be knocked down to a Colony Capital.     You clearly have some code to re-designate another planet a civ's capital,  so if a civ loses its capital city it should be easy to just bump the re-designated Colony Capital up to Capital City to compensate.

Hey, I said that week or so ago.  Totally silly to be scouting with Princess or Overlord ships.

I'm on 3.04, and I think the building of additional Central Bank (have not yet had the problem with Computer Core) is probably due to loading a saved game rather than a faction getting defeated.  In my latest game I am able to build another Central Bank by turn 20.  I have saved, quit the game, and reloaded.  I have not seen any notifications of factions being destroyed.

Frankly, I was confused about that too until I saw the wiki.  And I'm still confused about why I haven't gotten the "Trial by Fire" Steam achievement, which says "Successfully complete a crisis".  I'm hoping I'll get it when I get a crisis manager.

Nice         

I noticed the last released patch 3.04 reduced ram requirements;did that come with actual optimizations or was simply a face value change?

Have you tried to repro this while using custom factions? It just a thought since most of us do use a custom faction or 50. Happens to me in every game I play at some point or other.

EDIT:

I only play with custom factions (Civ builder factions now, I ported all my xml factions over)

I played a game with a ton of civs, researched to planetary invasion and then gifted it to everyone (made me feel a little dirty). And then watched them begin to kill each other. Civilizations were getting wiped, but I never got the ability to build another Computer Core, Central Bank or any other unique building.

So I'm still not sure how to repro the issue.

I have had this happen many times.  I was sure it happened when a planet was lost by a race, then it would happen when everyone was at peace.  I guess it still could be caused by a planet lost to influence, but I think it is probably something else.

I had one game where it happened where I saved the saves and tried to reproduce it and see what caused it.  I have posted the information in several places, but I think SC:O caused the posts to be ignored.

Here is the text I posted on Discord and the link to a save and more data.

"After playing a while, I found I could build a second Import Export Center.  I have a save before that, so I loaded it and played to see what allowed me to build a second one.  It never happened again.  There were a lot of wars going on, so I thought it might be related to a planet with a Center being conquered somewhere.  I did some testing using the console a found a way to allow a second Center to be built that worked every time.  It involved destroying a planet with a Center.  For some reason that allowed me to build a second one.  I have a zip file with the save and a text file giving full instructions."

In the save in the link I just posted, I couldn't build an Import-Export Center.  I then used the console to destroy another race's planet that had one.  I was immediately able to build another one.  Something in the game code allowed me to build a second one after another race had lost the one they had.

After I built my second one, I couldn't build another one.  I then used the console to destroy another planet and could build a third one.

I hope a dev will do what I did and see what is going on with the code that allows that.
