"That could make San Francisco-based Zynga the third-largest U.S. video-game publisher by market capitalization, bigger than Take-Two Interactive Software Inc., the maker of crime-game franchise Grand Theft Auto."

Awful. A company that uses sleazy monetization tactics (until someone called them out on it) and blatantly ripoffs games from competitors will be worth more than one of the most innovative game developers.

Mobwars > GTA?

I guess the valuation though reflects the business fundamentals of social vs console gaming.
