As it turns out, Activision's Call of Duty: Advanced Warfare is just one of more than a dozen PlayStation 4 games that does not support Sony's new Share Play functionality. A report today from Eurogamer documents the many games, in the United Kingdom at least, that block Share Play, and it includes big-name games such as Call of Duty: Ghosts, Tomb Raider, Minecraft, and Thief, among others.

　　Share Play is one of the most exciting features included with the recently release PS4 2.0 update. It allows two PS4 owners to play the same single copy of a game over the Internet. The console owner is designated the host, and is able to stream gameplay to another, guest console. This person can even give up controls to the guest, essentially allowing the guest to play for free.

　　Sessions of Share Play are limited to 60 minutes, though the host is able to reset the feature at the conclusion of each period, able to effectively loop it indefinitely if they want.

　　Although Sony at one time promised that Share Play would be supported for all PS4 games, the company has since clarified that developers can disable the feature at will.

　　For its part, Activision says its engineers didn't have access to Share Play before it was released last week, so the company was unable to "evaluate it to see how it will impact the experience across all modes of play." Looking ahead, Activision did not rule out allowing Share Play for games such as Advanced Warfare and Call of Duty: Ghosts in the future.

　　The 14 games that block PS4 Share Play are listed below.

As Eurogamer points out, Middle-earth: Shadow of Mordor was blocked from Share Play before PS4 update 2.01, but now it does support the service. It's also possible that publishers do not want guests to experience their games with worse visuals and frame rate, and are blocking Share Play for that reason.
