Videogame stocks careened lower Wednesday after two of the industry’s biggest publishers showed how difficult it is to escape the long shadow of “Fortnite.”

Shares of Take-Two Interactive Software Inc. sank 14% after the company delivered an outlook for its current fiscal quarter that didn’t meet Wall Street’s expectations. Late Tuesday, Electronic Arts Inc. also disappointed Wall Street with its outlook; its stock fell 13%.

Both Take-Two and EA reported higher profit for the latest quarter. For Take-Two, the share-price drop stung as the company had stellar sales of its long-awaited Western shooter game “Red Dead Redemption II,” which has sold 23 million copies since its release in October.

The industry selloff Wednesday hit other big game makers. Activision Blizzard Inc. stumbled 10% and Ubisoft Entertainment SA fell 9.5%.

The market’s harsh reaction underscores the increasingly cutthroat nature of the videogame industry. Players are spending the bulk of their time and money with a just handful of games—a trend game companies have fostered themselves. They continually pump out new content to extend the life of their most valuable properties, generating sales of virtual goods along the way.
