The countries who defect follow a certain logic: first a region (Europe, Southern America, etc.) that has Alien Infiltration assigned as a possible mission is randomly selected for the mission. Afterwards the first country who defects is the one at the top of the list of countries of that region who is still in the country. So some countries (US, UK, China, Nigeria) will always fall first than others.
This is how it works on the original game, I can't remember though if on OXC the selection is still made from the first country who is still in the Council or if it is randomly selected from all countries of the region still in the Council.
Erhm...Ok Ill repeat it again: Its neither about money or how the game works. I know how it works. I Just want to know what the experiences have been, not to reach any conclusions....
Actually that's one of the points we should look into deeper. Because if the said region which is chosen only has one country, you will only loose it and aliens are all over the place (e.g. Region South Africa).
It would be better if the Aliens would try to infiltrate all countries in the region and then stop the mission and put it at the end of the list of regions or in a list of already infiltrated ones. To get the country back or better free the people X-Com would have to attack first the alien base there and eliminate it and second do a couple of special missions in the defected country to eliminate aliens undercover and "convince" government officials (probably at gun point) to withdraw from the agreement with the aliens and stay neutral. Maybe a miniatur Version of the Alien Brain is set up beneth the goverment parlament and the people there get mind controlled or something like it.
That would be a cool idea!
Meh, as far as I understand its not mind control or total enslavement. Its a one sided pact. The humans 'think' they will get a good bargain while in reality the get the short end of the stick.
Also IMHO the defection should be permanent (as is), but there has to be some short of prevension for example eliminating the UFO wave that goes to do it (and they are a lot, I shot down 7-8 in my current play through and still lost Canada somehow) should postpone the mission for at least an amount of time.
