Players of Diablo 3 will not play be able to play the same characters on their PlayStation as they do on their computers. In a battle.net forum post by Vaeflare, it was confirmed that there will be no cross-platform play when Diablo 3 is released on the PS3.
The post goes on to say that Blizzard won’t allow an analog controller hookup to be used by players of the PC game. This is a disappointment for fans who are tired of the “mouse mashing” that is such a big part of the series. If you want to use the controller, you need to get the PS3 version. The same goes for anyone who was looking forward to using their keyboard and mouse from their couch. It is a completely different UI, so a completely different method is required. If you play Diablo 3 on the PS3, you use a controller. If you play on a PC, you don’t.
It would have been cool to be able to upload our elite Paragon super wizards to another platform with cross-platform play, but alas, it won’t happen. Another big question that has yet to be answered is “Will Diablo 3 have an offline mode?” We should find out much more when Blizzard comes to PAX East in March.
