Got my Dead Island Riptide on PS3 delivered today. I must admit the framerate isnt as good as 360, especially in the prologue but I am still happy to play it. I loved Dead Island and more of the same is a good thing for me! Plus I decided to import my Level 43 Logan and now have half of the skill tree completed from the start of the game. I thought my character might be hard ass but all of the zombies and weapons have levelled with me so its just as challenging! 
May the NFOrce be with you always.
