It is not true that the freebee offered by Ubisoft is the the same, it is not, over the Gog game is better. I have all the games produced by Ubisoft..,and now listed by Gog including Complete Chronicles and i have been playing all the games over a twenty year period and my experience with the Gog game is good.I cannot say why the game is better, i do not want Ubisoft to know.
