I've noticed people discussing the rapid nature of Fitzroy's development, but as I was playing the game it made sense to me. Here's my line of thinking: Elizabeth and Booker casually jump into alternate dimensions to save the gunsmith. First, to a reality where he is still alive, and then to another where his machines are not confiscated, without any thought to the other changes that were necessary for those worlds to be different in the way Elizabeth requires. Chen Lin is alive in reality 2 because the Vox are stronger and the Founders never got to him, and then in reality 3 they are stronger still. Why are the Vox stronger? Because, at least in part, in each reality Fitzroy is different. Fitzroy 1 may never have been on the path to lead the Vox to full-scale war, but Fitzroy 3 is a psychopath. Fitzroy 1 does not develop into Fitzroy 3, she is still back in reality 1, waiting for her guns that will never come, losing her battle.
I think it's a truism that in general, nobody has any proper understanding of the time, work and cost of any job other than their own. As a result people have an unrealistic view of how much money is needed to make anything, including video games.
What really got to me in that final scene was the "Clementine will remember..." captions. Before, they were always there to let you know that your decisions would affect the story down the line. Now they are telling you that Clementine will remember your advice after you're dead.
@bearklaw19: I had worried about Dead Space before I bought it, and there are still parts of 1 (and to a lesser extent 2) that I wouldn't look forward to if I replayed them today, but it's not the scariest game out there in my experience. I bought both Siren games for the PS 2 at the same time (when 2 was new), played about an hour of each and sold them again. Then called myself a coward and bought them again, and still they sit, in my pile of shame, waiting for me. I've since finished Blood Curse on the PS3, but those two originals, man. Spooky as hell.
Pontypool was also released as an audio drama, listenable here: http://www.bbc.co.uk/worldservice/arts/2009/06/090617_pontypool_audio.shtml. NB: This uses the audio from the movie edited and remixed to produce a shorter version of the story with a different ending.
Another thing about Pontypool - if you watch it and like it you should listen to the director's commentary. At one point they discuss the plot of the (as yet unmade) sequel, and it's fascinating to hear the direction they were panning to go in.
