I Like the Idea. improves the game a little bit more.

Hope if the work on that system they also made a Change in two Closed borders on for unarmed Ships an one for armed Ships.

A major difference between Civ, etc., and Galciv is that space is porous.     "Trench lines" and "bottleneck defenses" don't apply.    Violation of one's ZOI should have diplomatic consequences, and there should be a diplomatic option to demand ships to leave friendly space or face DoW (which overrides any ideology block).   But that's it, in my opinion.

I would echo Bamdorf's post, but Bamdorf already did that for me!

Personally what i see is closed boarders is me declaring i dont want you in my space. the biggest thing here is that it lets the ai know how i feel so it wont ask for open borders we can be friends just dont come over to visit. 

now i would also like to see some options for ships that break closed borders if i can 'catch' a ship violating my borders i should eithar be able to

arrest the crew and confiscate the ship ( malevelent )

Give them a ticket and escort the ship to a selected border ( pragmatic ) ( the ship joins your fleet as a non combat ship you can direct its movement until you exit your space at which turn its returned to owners controll)

give them a stern warning and let them go with instructions to head To the nearest border. 

I personally don't like the idea of having closed borders in the form of auto-war declarations. Increased diplomatic penalties would be work though, and perhaps even some version of a cold war state where if another civ's ship is in your territory you can destroy it without declaring war on the ship's owners.  I do like the idea though that space is exponentially more difficult to patrol and monitor then land, so interstellar borders are near impossible to enforce.

I already see a diplomatic factor that says it is a minus for having ships/starbases in their space without Open Borders.  Is that what some people are asking for?

Exactly how I used to play Civ; I found the AI wouldn't get pissy with you if you didn't give them open borders, and they basically couldn't scout your land, and then become envious of how awesome it was.

Would I enjoy a similar feature in Gal Civ?

You bet your boots.

I've been sick to death of the AI stealing my anomalies for YEARS.

In civilization 3 this was alright,  then it became annoying. First of all it hibders scouting,  because nomatter what you do you can't explire. Second if you didn't trade for open borders the ai would get but hurt because it couldn't figure out how to do anything else diplomatically. The way it was in civilization four it didn't make sense,  because if you didn't have a military you could keep a super power who didn't respect you out, this if fine,  not great if in order to keep people out without a declaration of way you have to catch them first. What i'm saying it is a miner addition at best,  or at worst it is a very bad game mechanic where a super power can't enter a territory where all he wants to do is cross when he has a fleet of huge hull ships,  where as the other guy has one tiny hull fighter. I think it makes a nice idea where ypu can threaten,  but can't keep them out without catching them.

Now as long as you understandi'm against the way it was done in civ four we can move on. Now as far as passive closed borders where you have to catch the ships unless you declare war on the offending faction you would arrest them with options to do from arresting them. Once caught i should have an option to resist arrest where i choose to fight it out. Haveing a united proposal which i could vote against wpuld be alright. Having this as a game or mod option which i probably not download this mod would be alright.

I do think if you had closed borders this wpuld be a diplomatic negative against you from everyone whowasn't friendly with you. I think things like routs,  and certain kind of ship exemptions shpuld be allowed on diffetent kinds of closed border treaties,  and if you didn't give ai's open border treaties their should be a diplomatic hit. 

Just to reiterate if you are trying to cteate a unpassable border without trying to protect it theni'm 100 percent wholeheartedly against it. If you are trying to tell me to get out of my territory.then that's fine as long as you can't do anything unless you can catch me, or declare war then i don't mind the idea.

Now as far as mechanics goes there would have to be a grandfather clause in case of planets already colonised,  and starbases in your zone of influence. 

There are two major things about that UP Resolution that I hated, as well as a minor thing or two that annoyed me. Firstly, cultural influence boundaries and actual territorial boundaries did not necessarily align; those colonies of yours that I've managed to bring under my influence? Those are in "my" space, based on how the UP Resolution defines things, and I can mass ships next to them for the turn-1 attack when I declare war without any issues. Meanwhile, any ships that you put into the area to defend those colonies? Those get kicked out of the area because it's "my" space. And secondly, it teleported ships without costing them any action points regardless of how far the ships had to move. I'd much rather see the ships put on autopilot or see them lose a number of actions related to how far into enemy space they were than magically teleporting them out.

As far as the minor things that annoyed me go - I'm a big evil space empire, so evil that the indicator is pushing past the end of the evil scale, my empire's power is such that everyone else in the galaxy combined is weaker than me, and yet I cannot ignore this little resolution despite no one having sufficient power to enforce it if I were to violate it? I have no reason to leave the UP aside from that since I effectively control the place, but I can't get rid of this nuisance? I'd really much rather these kinds of things were more "voluntary but with penalties if you fail to comply" than "you must comply regardless of the circumstances and you have no choice in the matter aside from voting on the resolution or any potential repeal the next time it comes up, and oh by the way the resolution you vote on is random so good luck on getting that repeal going."

I can't talk about endless legends,  but i can talk about endless space,  which this sucked it stopped exploration in the early game. The closed borders you described is the problem where to rnter one's space you either had to have an open borders agreement,  or declare war. This can only bting a hindered atmosphere to the game. This is one of the drawbacks to endless space,  and civilization.  

Now the way it was done in civilization three where you can threaten an opponent to declare war on them. If i chose the option to move out manually or automatically it did. If i chose to ignore it it let me. If i chose to say no it let me. 

If i said no, or ignored you then you had a choice to let it go,  or go to war with me. Either way there was no magical hand keeping me out of your territory. Now you want to add an option to arrest me. I only like this idea if you use a ship that have to catch me if i refuse. I like the idea of closed borders anouncement to other factions. I also think you hsve to see me. 

I have some ideas about having different kind of open borders agreements. Like establishing trade routes that you can move through. Picking what kind of ships to restrict.  If you arrest.me I have a right to resist. About diplomatic penalties that depends how other factions feel about you, and what kind of closed border agreement you have depends on how much of a penalty there is.

Now you are talking about a passive closed border which is fine. No arbitrary fields around empires.
