Zynga pulled a tantrum and retaliated with a frivolous lawsuit. They won't get anywhere with it.
EA will wipe the floor with Zynga and probably get a fat settlement from them including having them take down "The Ville" ripoff. It will only help establish EA as the new force in mobile and social gaming.
I'm not entirely certain that EA has any real legal ground to stand on with their lawsuit, as there has been a never ending stream of 'me too' copying of gaming ideas. Could Id Software sue ATVI, EA, and nearly every other company that has made an FPS? Could Taito sue all the companies that created all those 'shmups' in the 80s and 90s? Could Capcom sue Namco, Sega and everyone else who made a one on one fighting game? etc etc...
Now, don't get me wrong, I think the suit is justified as all ZNGA can do is copy other people's ideas in a vein effort to get rich off of the ideas of other people. I just don't see the lawsuit as anything but grandstanding on the part of EA. I, for one, appreciate the sentiment of the suit, even if it won't bear any fruit, so to speak.
