Regarding historical accuracy I look at it this way. A great many games completely eschew reality. They're based upon total flights of fancy. Those with some basis in historical fact may or may not attempt to follow the events exactly, copy the culture in exa🅺ct detail, etc. I have always viewed games with RPG elements as works of fiction. As such they're quite similar to novels. In a sci-fi novel based upon an historical event the author may or may not hew to the facts exactly. He might instead opt to create a parallel universe or alter the facts slightly to create a different outcome. That's the fun and, to me, interesting part of many novels. Why should games be any different? If the UbiSoft team responsible for Assassin's Creed: Shadows wants to alter history good on them. Why not? There's no rule written in stone that says they should adhere meticulously to the historical record.
