I haven’t finished any game in the series so I can’t fully comment, but if my memory serves me right the control scheme prior to maybe AC4 was absolutely awful. There’s a really good video on YouTube that pretty accurately describes my feelings on the series from what I’ve played. I don’t remember exactly who made it now but I want to say either VaatiVidya or Iron Pineapple. If I find it I’ll edit my comment and include the link.
