I just want to see the evidence that gets brought up at trial. For example, it's quite likely that we're going to see internal Zynga emails that say, "Let's copy Mob Wars," or, "Let's copy Tiny Tower." Specifically, they'll introduce one that says, "Let's copy The Sims Social," but it would really behoove them to introduce as many of these emails as they can, because it establishes a pattern. Juries and judges love patterns. But that's beside the point.
No single judgment can really bring Zynga down, not even when that judgment is on behalf of a company as large as EA on a license as large as The Sims. Tens of millions of dollars, tops. Zynga has $1.2 billion in cash and short-term investments (EA only has about twice that, actually). However, if evidence is introduced that functions as an admission of guilt with regard to copying games and EA wins... there's a lot of lawyers who would take cases from small development houses whose games have been cloned and do the cases on retainer, because there's already evidence and precedent.
As it stands, Zynga's been working on three unprofitable quarters, a potential lawsuit over a stock sale by Zynga officers and directors, and the COO got removed from his position last week. I wouldn't say the company's in free-fall, but they've got the 'chute on and are staring out the door of the airplane. Again, however, a lawsuit -even one from a company as big as EA- isn't going to kill Zynga (unfortunately). Their operating losses just aren't enough at the moment to cause the company to crumble under the weight of lawsuits, much as I might like to see that happen.
At first I saw this as being a quagmire like the Apple v. Microsoft "look and feel" case from 1994, but that was a case in which Apple was asserting claims over ideas (not copyrightable) rather than expression (which is copyrightable). In short, EA can't really copyright a city-building game or an anthropomorphized Tamagotchi (which The Sims functionally is). But expression being copyrightable, all you have to do is look at the expressions of the Sims characters versus the characters from The Ville (these pictures are available in the text of EA's filed complaint, which is eminently readable by anyone even without a legal background), and you'll see that those expressions are near-identical. Yes, I'm getting a bit literal with the "expressions" thing, but it fits especially well in this case.
