One thing I've noticed (at least for me) is that if I don't play the game at least every other day and come back to it like a week later or so my timing goes all to hell.
I picked up LOR: Return of the King... yeah I know there will be a Special Edition and an ULTIMATE RETURN OF THE KING IS GREATER THAN RETURN OF CHRIST~! Edition but that's ok. It was at Walmart for only $15.
