Well Gaunathor, I disagree with the thought of borders in GalCiv2, I don't like it very much.
I'm generally a peaceful fellow but if I find you inside my lines? Your dead.
I acquired large amount of anger and stress when I saw torians stealing worlds inside my borders so this game is very unsuitable for enjoyment purposes. Because i see borders as same as my home, your trespass in my home? your dead.
It's very unfun. It's more bad than SId's CIv series AI doing dick moves like settling a city inside your borders that tiny empty spot inside your borders and then whine about tons of soldiers because it's basically your land especially when the owner of the little cardboard house inside your land is 100 turns away from it's homeland.
And more worse is when they cry about too many soldiers near the said cardboard shack when it's my garrison zone away from main borders of real cities.
AI does it to get a NAP forced on you against your will, but the joke's on the ai, I always dow immediately and raze the offending shack.
AIs that respect my borders have a tendency to never get dow'd on by me and survive to the end of game and still not be killed by me because they're cool fellows. Douches who disrespect have a tendency to end being forcibly fed their own medicine by my own soldiers with me not respecting their borders and declaring ownership of their own lands because they did it to me.
Civ series is bad enough but at least you can actually notice the trepassers fast enough and kill them before they can even get near you.
But compared in Galciv2, they can sneak in like mexican immigrants and you won't notice them until its too late. I don't like this at all. All this advanced technology and not a single notification of a colony ship sneaking in?
They got in without my permission. They must die if everyone else don't like it, well sucks to be them doesn't it? :3 If i die, so be it, at least I died with my honor intact. AI is useless anyways, they don't even understand that torians trespasser not me in the first place.
And there's not even any open borders agreements at all in this game. If i opened my borders and torians colonized the uncolonized worlds in my borders, so be it, that's my own fault.
See? stupid wall of text. China called me and they want their wall back. That is why I'm uninstalling Galciv2 after I kill off the torians.
