The legal battle between Zynga (Nasdsaq: ZNGA) and Electronic Arts (Nasdaq: EA) is intensifying.

Last month it was EA alleging that Zynga's The Ville was infringing on the copyrights protecting its own The Sims Social. These are two of the most popular games on Facebook (Nasdaq: FB) these days. The Ville is attracting 29.3 million monthly users, more players than either CityVille or FarmVille is drawing these days. EA's The Sims Social is reaching 13.4 million monthly gamers.

Zynga countersued on Friday, alleging that EA's CEO was seeking to bar Zynga from hiring EA employees after losing many executives and developers to the social-gaming leader. These "no-hire" agreements are illegal in California.

The timing of the countersuit is ironic, since it's Zynga that's having a problem keeping its employees, and that includes former EA executives.

Zynga has seen a whopping eight executives resign this summer. Whether it's Zynga's decaying stock price since going public at $10 back in December, working conditions at the company, or just the growth prospects of social gaming in general, this isn't the company's finest hour. It may seem silly to see Zynga portray itself as the market darling that traditional video-game executives want to work for, but we're obviously talking about the past here. Just last summer -- shortly after Zynga filed to go public -- analysts were throwing out valuations as rich as $20 billion. That would be more than Activision Blizzard and EA combined.

Zynga's valuation is a more somber $2.4 billion these days, and a good chunk of that amount is backed by cash raised during the IPO.

Zynga's come a long way, and that's no longer a compliment.
