Any historical depiction is automatically ahistorical and always reflects the ideologies of the time, this includes Ubisoft specifically choosing a black protagonist and this also includes the ahistorical Western white-man-dominated depictions of history these chuds were exposed to as teenagers and internalized as 'correct' and 'default'.
It's kinda frustrating to an extent that either side in this stupid gamer debate claims some closer simulacrum of history.
I completely agree and this is something everyone should remember. Even so, it's fair to say that there is a spectrum when it comes to the ahistoricity of any given historical depiction. A work can be a bit off despite the honest attempt of the artist to make it historically accurate or it can be a grotesque mischaracterization that distorts the context beyond any semblance of the historical reality. G*mers tend to demand the latter while pretending they're the ones championing accuracy.
