Maybe I just missed something, but I didn't notice anything in that trailer that never appeared in the first two games.

I will say that I will never understand the flack that Xenosaga II gets. It may not have been what was originally envisioned with the series, but that doesn't change the fact that the story in II is amazing. I may just have differing tastes than a lot of people, but I was never bothered that the overall plot wasn't moved very much in the grand scheme of things. I was too busy being in awe of the story being told at hand. The only thing bad for me when I last played it was how jarring the change in visuals/voices were after playing II immediately after I. Also I preordered II when it first came out specifically for the preorder bonuses. When I went to pick up the game they told me "Sorry, we ran out. Those were only for the preorders." One of my worst days in my childhood, haha. Also, the visual/voice change is pretty jarring when playing II immediately after I.

I think I'm going to go back to playing through this series again now that I have some more free time with student teaching being done for me.
