A fun example of an island which is not disputed: Märket is a small uninhabited island located between Sweden and Finland. It's divided between the countries and Finland even built a lighthouse on the wrong side of the border!
Another example i the island Kataja, which didn't even exist when the border between Sweden and Finland was drawn, but now sits on the border.
Didn't have time to play a full game, but it played quite well. As usual with AIs, it made some strange decisions in life and death situations and ko-fights.
At least in Sweden and Finland it is recommended to refrigerate eggs. This way the eggs are edible up to two months, even though the packaging (based on EU rules) says 28 days.
I've been playing for about 10 years (still about 10k). I usually play on http://www.dragongoserver.net, since it is asynchronous and I sadly don't have much time to play.
