yeah but i didn't know that the second one was on the dreamcast if i'd known i wouldn't of btohered saying that.
and shenmue 3 is susposinly in this being realeased on xbox though they have no publihser or a date of when it to be realeased yet ehre look yourself
shenmue 3
but like you said no shenmue 1 on xbox so i suggest getting shenmue one it is amazing i don't think i have completed it yet but it is amazing you will love it.
shenmue two is great too but shortend down alot..
buy a dreamcast go onto shenmue 1 then buy 2 for dc then if shunmue 3 does come out on xbox or ever come out then i guess u will have to buy that machine if you want to continue unless you have it already.
good luck
