I'm not sure how I feel about this. While I liked Heavy Rain the first time I played it. Trying to play it the second time it comes off as a boring mediocre title with a decent story and premise. The only thing that made the first experience enjoyable was the belief that what you did mattered to the story. Which it only did in really really minor ways.
I’ve never been a big fan of QTE any way. I somehow end up feeling like those experimental monkeys sitting in a lab being taught to push colored buttons in sequences.
What I want to see is true gameplay changes for your actions. Alternate solutions to puzzles and ramifications for mistakes. For instance the ability to play multiple characters who can die. In which case you have different paths through the game with the characters that remain alive.
Also it would be neat if you can switch between the characters. Like in Day of the Tentacle. That way the different characters are needed to help each other. For instance one needs to get to a panel and turn off a electric fence for another character to advance or escape a Dinosaur.
