I love Godfather (I just got it for Easter) and I am gonna get PoP soon. Godfather is a great game, but if you haven't play PoP series (like me) keep it.
just keep pop ,and buy godfather. Godfather is great ,and besides pop being a port of last years game with added controls its still suppose to be good. I'm grabbing it after paper mario. i would buy it now if paper mario wasn't due out.
