Come June, Facebook (META -0.33%) gamers won't have as many titles to choose from. Electronic Arts (EA -0.87%) is closing Facebook editions of three of its social games: The Sims Social, SimCity Social, and Pet Society.

Some games will remain; notably, titles published by EA subsidiary PopCap Games. Even so, between this and Zynga's (ZNGA) recent move to direct more gamers to its own site, the implication is clear: Facebook isn't the gaming platform it used to be.

Investors shouldn't see this as a reason to sell, says Tim Beyers of Motley Fool Rule Breakers and Motley Fool Supernova in the following interview with The Motley Fool's Erin Miller. Gaming has long been an interesting feature of the social network thanks to its partnership with Zynga, but Facebook's future depends entirely on attracting and engaging mobile users. Desktop games are a sidelight, at best, Tim says.
