Honestly, I think calling your game <x>-ville with Zynga around is just asking for trouble.
It's not like the Notch Scrolls trademark issue where it's a bit iffy as to whether it is misleading. Using ville as a suffix right now really is going to confuse people.
However, 3x the profits realised from the game? Seriously? That's kind of over the top.
Oh, and having just read into the actual document from Zynga they show a comparison of the Logo Kobojo is using for Pyramidville. There is no way this isn't intentionally trying to mislead people.
