I don't have a great memory don't think I have every played an update from a save file. I start from scratch every time to remind myself what happened, and possibly try making slightly different choices. If it is a game I have played many times, or if I played it really recently, I will sometimes skip through some of the dialog or go through it really fast as a recap. Even if I remember everything an where I was at, I just like the continuity of getting the whole thing starting from the beginning. That can be troublesome though with longer games or ones with multiple seasons. Feel like I can't play the update to sunshine love chapter 3 until I go back and re-play chapters 1 an 2
