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.<p>However, 3x the profits realised from the game? Seriously? That's kind of over the top.<p>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.
Yep, just take a look at the logo comparison in the scribd document - definitely no questions on if Zynga should be doing this or not (they should). It's one questionable-ethics company suing another questionable-ethics company, nothing to see here!
