Now that I more awake than when I replied to your yesterday, I realized I got all mixed up and was actually thinking on the Takemizu Village Lots for a very japanese-ish look ROFL (sorry!! I had a long day at work rofl) tho the Twikki island is better and larger, and the old temples and such could work really well too.

There also the Moonisland (or something similar) template that's really nice because has water all around.

And about the "killing" maybe you could take a survival approach, more than a straight up bloody killing everyone. Maybe kids could disqualified if their need and/or asp. goes to low, or something of the kind.

Dunno. Just throwing ideas ;) I'm sure I'll be awesome anyway you do this.
