Horizons,
You haven't played II yet?!?!?! It's even better than the first in so many ways.
Since it didn't come out in the US for the Dreamcast, I download a program off the internet, burned it onto a CD, ordered the European version of the game, used the boot disc to get around the regional requirements and was in gaming heaven.
Now having just purchased an XBOX last month, I picked it up for that and played thru it again. Loved it even more. Plus it had some nice additions to it and an English voice dub, which the European import did not (only subtitles).
Also, with the XBOX version you get the DVD Shenmue movie, whichs takes scenes from the first game and put them together for a movie, almost 1 1/2 hours long.
