FacebookSocial gaming is just barely old enough to be called an industry, but already the battle lines are emerging between major players Zynga, Playdom and Playfish.

Playdom and Playfish, since their acquisitions by the Walt Disney Co and Electronic Arts Inc respectively, have focused on bringing their branded intellectual property to the social gaming world. That could include a possible Playdom game with Marvel superhero characters, or the Playfish version of Monopoly now in the works (EA owns the digital rights to the board game). 

Zynga is by far the industry leader in revenue and size, but it lacks the deep vaults of intellectual property that come with being part of a conglomerate such as Disney.  So it has taken a different tack by focusing on marketing tie-ins with the likes of McDonald’s and convenience store chain 7-11. “One of the things that we really believe is going to happen is we think there is going to be much more connection between the virtual world and the real world,” Cadir Lee, chief technology officer for Zynga, told Reuters.

As Reuters reported on Sunday, the social gaming sector is bracing for a new wave of acquisitions.

With that development in the works, competition in social gaming continues apace.
