Despite what I said of Heavy Rain's predecessor, Indigo Prohphecy, I don't really mind this sort of gameplay that much. So long as 2 conditions are met:
1. The quick-time events are only used for real, physical actions, and not to drive a character's thoughts. I mean, in Indigo Prophecy, there is a scene in which you are examining a corpse and for some stupid reason, they put in a quick-time event representing the detective's thought process. What the fuck am I doing during this sequence? Making the gears in her head turn?
2. Make sure the story actually makes sense. Again, Indigo Prophecy is the main reason that I'm wary of Heavy Rain. Its made in more or less the same style, and its even being made by the same bloke that made I.P. And as I recall, I.P.'s story ditched the interesting murder mystery with a twist in favor of "Bwwhahahaha! I'm an evil tosser!"
