Farenheit / Indigo Prophecy got moving an awful lot quicker. That whole section a the start of Heavy Rain where you have to (really slowly) walk around the apartment doing mundane stuff nearly had me turning the game off. It may be because I have played the former game quite a bit, so I aleady knew how the controls work.
My brother worked at Sony in Wavertree as a tester (before he got a real job) and can pretty much complete Heavy Rain in his sleep. They went through the initial release loads of times, then just when hey though it was all over, they had to do the Move version. When the move version was done they all got an email saying that they wouldn't be listed in the credits as testers because they were agency staff. I think that it is fair to say that he hates the game.
