NOTE: I have not read this thread. I have no idea what is in it, since I haven't watched the movie yet.
However, we played the Matrix PS/2 game this weekend. Excellent. I love the implementation of "bullet time".
The game follows Niobe and Ghost. There are a few interesting bits towards the beginning (we didn't get that far), one of which is a comment that "Zion lasted 72 hours last time." This led to speculation (my brother in law *has* seen the movie) that the world Zion is in is just another layer of Matrix for the people who get wise to the interior one.
After I see the movie, I'll come back here and read the responses. ;-)
