OP is missing a few like Cole Macgrath, Sly Cooper, or Sweet tooth, but whatever. Sackboy seems to make the most sense, but playstation doesn't really need one. They've been doing fine without a Mario level mascot. However if one had to be picked right now, probably gonna be Sackboy. But then again, there is gonna be a Sly Cooper movie soon enough so that puts him back in the running.
HAHAHAHAHAHAHAHA no. A mascot has to come from a GOOD game.
Well since PS4 has no games, and Infamous has a new character, it's probably a Helghast Soldier from Killzone. Pretty bad mascot, but that's what happens when you have no games.
They've never really had a set in stone genre that's held major popularity. I think Kratos would be cool for their mascot, but those games were washed up years ago.
No gameplay and horrible story/dialogue/characters
Except for the part where there is gameplay. And the characters/story really aren't that bad. I've only played the first tho, but I heard it gets better from there. Not trying to derail the thread or anything...
What little gameplay there is can be equated t you being a small child whose hand is constantly held by a large man who punches anything that comes near you
