With inFamous already having the photo mode and now The Last of Us and even Driveclub to get it, it seems to me like all the 1st Party Games will be getting this mode. To me it just seems like they took the code from inFamous and implanted into The Last of Us. So Sony should give this code to 3rd Party Developers and make it a PS4 exclusive thing.
Think about GTA V with Photo Mode, the city is huge and I would love to get better angles on the city.
Yes I know inFamous isn't the first game to do this, saw this in Dragon's Dogma but I think other games will follow with this but I think Sony should go to 3rd Party developers first, give them the code in exchange for it being an exclusive mode.
