Technically Assassin's Creed didn't pioneer the "genetic memory" thing. That's waaay older than Ubisoft. It was the premise behind the Bene Gesserit's abilities in the Dune books, and I think Carl Jung posited it at one point too? Can't recall. It's nothing new, and it's still complete bunk. It's cool as hell for scifi purposes, but totally crap scientifically.
