have you not played an Assassin's Creed before? Even if you ignore the premise of travelling back in time through your genes to see specific moments that wouldn't have any impact on your genetics (it literally makes no sense), look at what they did with Leonardo Da Vinci. You murder a pope at one point. And, and we may disagree here, I don't think the illuminati have been secretly controlling the world while in a perpetual war against the Assassin'sYet the same company invests millions of dollars in recreating the most realistic cathedrals, mosques & cities (along with the populations & their clothing) based upon mountains of research vis-à-vis the era in question. Yet no, f-it, realism is not something Assassin's Creed is interested in. So let's have everyone & their momma in the character creator.
Okay.
Also this is the 2nd game in the last few years (presumably from this team as lead) where you can pick different characters, it's not a new thing for the series.
