I was asked to put this up awhile back, after Episode III came out, but I forgot about it. =p
This is one of the first trailers released by Namco and Monolithsoft for Xenosaga Episode I back in 2001. What's really important about this trailer is that it shows that several plot elements, that show up in Episode II, were actually supposed to be included in Episode I.
Nearly all the content within the last minute or so of this trailer was cut from the final release of Episode I and instead incorporated into Episode II or III.
- The sword fight between Jin and Margulis.
- The silver robot shown standing up was never seen in the final release of Episode I. Many believe this to be an early design for either Omega or Proto Omega, which made its debut in Episode II.
- The footage of the child rocking back and forth never appeared in Episode I. The boy's name is Abel, and while he does show up in Episode I, it's only for about a second at the end of the game. He's shown stacking building blocks in a most unusual fashion, not rocking to and fro. Abel actually doesn't make a significant appearance until Episode III.
- The conversation between Jin and chaos on the porch.
The two facts that are important to note are the conversation between Jin and chaos and the fight between Jin and Margulis. Both of these events occur either partway and late in the game, leading many to believe that all of the content before and between these events was supposed to apart of Episode I, not II.
Of course, all this is matter of debate, and something for the hardcore Xenosaga fans to scratch their heads about. =)
