Hi, Tsavorite,
I did a "search" for a "Blackstone Chroncles" Download, and there seems to be NO "legitimate" sellers out there. I, myself have a BOXED version of the game, and if I remember, it ran ok on my Win XP computer. I believe that what AMAZON is selling IS the boxed version, and NOT a DOWNLOAD version. I advise you to STAY AWAY from those ILLEGITMATE Sellers on the internet.
