This is what those same settings give me now.

Are you kidding me???

Did you try rerolling a few times?  I'm not getting anything like that.  My settings are different but similar.

I've actually seen results similar to yours in previous versions, but they were rare & didn't repeat with rolling new maps.

Could it be that you have a mod installed? This looks like the one which gives you a huge single sector. 

Do not know what others might want but for me it is both.

Thanks for the reply Zabik_2 

Personally I'd like more advanced map options game layer within the game settings menu UI where you can change the fine details on the map settings some of which I mentioned yet still retain enough randomness with exploration.

I'm not interested in a map editor I'd rather spend my time playing the game.  The only reason I have resorted to using cheat codes e.g. fow and modding is because I can't produce the map settings I want and e.g. fow allows to see what is going on without playing multiple hours on a map.  Map editors remove the randomness and surprise which I want to maintain but yet still know how many sectors what size they will be and roughly how many habitable planets those settings will produce.  Knowing this also gives the player an idea about how long a game will last.  

In regards of AI I feel I have noticed improvement over the patches but in regards of sectors they should actively be trying to find entry points and militarize with star bases and fleets, particularly important entry points and send colony ships ,constructors etc to them more than they are currently doing so.  Some sector entry points will be more important than others, preferably it would be great if the AI was capable of evaluating the difference but this is likely only something in the human realm currently or would make turn times too long, but I'm sure some improvements could be made.  AI's on their own in a sector should be throwing everything they can to expand into other sectors.

It would be great if the A.I. was actually capable of achieving victory on anything but the tiniest of maps or because of prestige calculation issues.

After about 10 attempts finally got my own sector.... but nothing like I wanted for the rest of the Galaxy.

I do not want a huge sector and the rest of the AI to be starved of expansion space.

Desired: 8 Medium Sized sectors with approx 2 Civs / Sector.

I was previously able to do this from the UI without having to go Mod an XML file.

FYI - I changed the Galaxy settings to "Large" this time hoping it would give more space for more Medium sized sectors.... but no. 

OK this may seem simple minded but that's because I'm simple minded.  To set up a galaxy, instead of vague terms about "the size of this" or "far apartness" etc.  why not 

1. Set the number of sectors

2. Set the approximate number of civs per sector.

3. Set the total number of civs. With a fairly narrow window of acceptable combos.

Done.

Of course the numbers will have to align so that it makes sense - and  you won't be able to select impossible combinations, like 1 civ per sector, 10 sectors and 30 total civs.  The player will have to adjust things until the numbers work, but it won't be hard.  In this example you would rarely get 3 civs in a sector or zero, but mostly 1 or 2.

Small variation is allowed on a random basis, but I can suggest as an example, say, 1.5 civs per sector with 10 sectors, and a total number of civs. Say in this example,  15 total civs.   That's the way I have thought about it but the mechanism actually provided is as I say rather vague and generally doesn't give me what I hoped for.

My further comment is that this seems rather trivial superficially but it actually has a ton of importance for a player getting the right "feel" to the game.  (How much exploration do you want?  How soon you will bump into other civs?  etc.)
