While Shenmue II for the Xbox is a solid game that offers some improvements on the Dreamcast version, it will mostly appeal to die-hard fans of the original.
You don't need to be a fan of Star Wars or of RPGs to appreciate all the impressive qualities of this game--but if you are, all the better.
No other game since Knights of the Old Republic has managed to deliver this excellent style of role-playing.

Sudeki is, unfortunately, more style than substance.
