There are english speaking spawning points off of the main three islands. The old lands are the K-isle, Siom / Lad isle, and the KDS isle. There are regions especially on the Siom isle, that are relatively unknown and empty of the throngs of people that can be found on the KDS isle.
For new and unexploiteded lands, there's Aki, Fu Put, Burgeo, and the slim chance someone can spawn on the Dhung isle in time to get massacared again.
I know that the little known lands would get a big help out of more people spawning. The way things are these days, the older characters watch the 25 year olds sleeping to death, while rare newspawns run off into the wilderness they think is safe from thier experiences with thier other characters, only to be killed by rhinos and cheetahs.
I do however like watching newspawns from the safety of my boat and taking bets on which animal will kill them. I've got long odds on turkeys for anyone interested.
If there was some way to increase the odds of a person spawning in a location, I'd take it. However, I can't really think of a way to justify that at all. That may be the only thing good that comes from babies, the people on these little known lands can spawn like crazy to populate it.

Reality was never my strong point.
