I've harbored an irrational love for Heavy Rain ever since Quantic Dream showed off that all sorts of rad tech demo at E3 2006. I've watched that thing at least a dozen times at this point, and get the same gut-tingling anxiety each time. I think it's mostly just an appreciation for how well that scene is paced, and I'm really hoping that sense of timing and tension translate into the actual game. That, and I hell of <3 movies, which it basically is in that form.
I always have a hard time bagging on a game when the developers are trying something risky (hooray for not being a reviewer!). I mean, I highly doubt this game will sell well at all--if it breaks 500,000 worldwide, I'd be shocked--regardless of whether it scores top markets or not. People just don't dish out for these types of games, as a rule. But it makes me happy when someone is willing to invest scads of money into a narrative-driven gameplay, especially if they're good at their jobs and know how to tell a compelling story.
As for MAG? Yeah, whatevs.
