Sony fans thought that Sony characters would be a bigger sales point than Nintendo characters in a Smash Brothers imitation game. Obviously, they were very mistaken.

sums it up nicely.

Not even close. What is available right now in the game is not even a fraction of the total amount of Playstation characters there is. I don't even know them all.
