OK, Zynga, we get it. You're insanely huge and popular and worth (wait ... seriously?) $10 billion. All Things Digital reports that as it ends a $500 million funding spree, sources claim that the mastermind behind CityVille is worth way more than the ubiquitous EA. You know, the guys who own Playfish and created Madden? They're only worth $6.2 billion, according to TechCrunch. Valuation is nothing more than an educated guessing game by big name investors as to how profitable a company is. Regardless, this number makes Zynga only second to Activision Blizzard as the most valuable games company in the world. You can cue the maniacal laughter now, thanks.
