Being one who would be up for RP in a decent historical place and who agrees it needs to not be accurate so much as hollywood, figured I'd throw in a few comments too. And definitely more Hollywood, I can't imagine stumbling across a log and reading a kiss while my mind fathoms halitosis and general dental hygiene of whatever era is being played (A got a bit of something from that kiss, must be a chewing stick you had before kissing me, how considerate of you .... alas, I did not have a chewing stick, my third molar is chipped from all the stone mill gravel in the bread, its either tooth or gravel).
I don't think too many places have claimed historically accuracy or authenticity, but as we can see here, historically accurate was applied as going along with historical setting, fairly early in the responses. Its a fare response to say its not advisable, but its also assumed a lot regardless of intent.
The comment about disliking the channel debate on accuracy is one I agree with, even if you say historical Hollywood interpretive fantasy, there is going to be disagreements on which is more accurate for theme and someone will always take the high horse of having to be historically accurate despite theme saying it isn't. Someone may even ask about obscure history that wasn't considered by staff and by the time they come back after finding what suits theme, a debate could be in full swing on a channel about what should be done by staff related to the question.
That said, I'm more concerned with the points brought up by @Pandora and @Tinuviel. The theme/staff could have addressed RED historical versus what the game is after relating to racial and ethnic portrayals, but regardless, there is going to be RED portrayals with wild interpretations (ie over the top stereotypes and/or gross misinterpretation). As the one that brought up the idea of an early stages Reconquista-Era joint at one point, it was apparent it would be impossible to diverge from RED. If the game tried to reduce the concept, it wasn't accurate enough, and even if it did, player pre-conceived concepts would dominate enough it would come up, most likely in some offensive manner. That and staff would be utterly busy trying to say, that's not our theme, over and over again.
Another note from me, and probably only me, I'd also be more worried that picking any era would be a rush for folks to get PBs/character inspiration from their favorite historical drama. Like as much as I enjoyed Jeremy Irons in The Borgias, I don't know if I want to see him used to play out an incestuous manipulative sort on a game (cause I watched the series, I want to be surprised, not replay an open book). I'd rather see something new to historical genre than something played out a few times; but I think its similar to the comic debate where people would rather see a Gotham re-envisioned due to familiarity rather than an original theme dark city comic game.
Like I've been enjoying Turkish historical drama ever since Magnificent Century made its way to Netflix, but shudder at the idea for something to play out magnificently in a historical setting (see Reconquista above), it would turn into some crusade era religious war concept where being group (race/ethnic/religion) x is somehow synonymous with must hate group y.
