Think video games are just kids' stuff? Well, a game called World of Warcraft, developed by Activision Blizzard (Nasdaq: ATVI), has 12 million subscribers -- at about $30 a pop. Those are the kinds of numbers that have made video gaming one of the hottest industries going today, and a favorite of analysts like Matt Argersinger of Motley Fool Stock Advisor.

Activision investors and gamers were shaken recently when two of the company's highly touted game developers -- the guys behind the enormously successful Call of Duty franchise -- left the company and started a studio funded by the competition, Electronic Arts (Nasdaq: ERTS). But the suddenly deflated stock price should not scare you off, says Argersinger; the employee defection won't blow up a business with this kind of armor. Not only is Activision's current portfolio of games impressive, its new 10-year development deal with Bungie (the maker of Halo) promises that the company's pipeline should be spraying golden bullets for years to come.

If your portfolio is in need of a little fun and games, think about going into battle with Activision. Watch the video here:
