This volume of content thing has come up in a few threads...here and over in the Ilithid one. If I do/choose X what will give more or less content.
I feel like this game is a bit unique as it is absolutely massive and no matter how you play it choices you make throughout are going to eliminate, create, or change pieces of content. If you want everything you are gonna have to play the game...I don't know, a lot of times and a whole lot of hours.
I am not sure if picking anything because it will give you 109 hours of content instead of 105 makes much sense. Or you get 18 more additional stories stories while giving up access to 14. Making numbers up but you get the idea. I really think people just need to pick what they enjoy the most, vibe with or really want to do and roll with it. No matter what you pick, you are going to have a ton to do, and you are going to miss a ton that your choices dont provide you.
