Oh. Didnt know that. Explains a lot, except how its a good looking game.
Basically, back in the ol' times when PS1 needed an exclusive title, Naughty Dog came in to save the day by giving them Crash Bandicoot.
But that exclusivity still remains. Can't really blame either party in this case.
It's good to see sony giving developers free-reign to do what they want like this though.
