Ok thanks for input. Wow. So I am looking at 2+ hours of even trying to remember what I did in both previous games. I am a detail freak so this is going to drive me nuts. I was very careful to make sure all choices I made in both previous games were exactly what I REALLY wanted to do. But this was 2 years ago lol. I have trouble remembering what I ate for breakfast yesterday. I want this experience with DA Inquisition to be perfectly accurate as to what I chose with both previous games. It's important to me.
Yes, it can seem like a lot of work when you are making your first World State.
What you'll find, though, is that once you've made one, you can make a second or a third very, very quickly. This is great if you intend to try more than one playthrough of DA:I, since you can see what effect it would have if you'd put someone else on the throne in DA:O, or if one of your companions had died in DA2, or if you hadn't helped a certain NPC etc etc.
In the long run, I think you'll find the time spent on creating your first World State will be time well spent.
