What takes you guys so long?

So this is my second character. I’m at act three before the 40 hour mark. My first play through I explored everything I could, did everything I could with it being my first play through. Looking back on my first play through and looking at YouTube videos I pretty much hit it all except some minor things like recruiting Minthara and I completely forgot to do Halsions mission but it looks like I didn’t miss a crazy amount of stuff and I’m finding stuff I missed this play through. What take everyone so long??? I see people who have 100+ hours on one tav. I understand talking to everybody exploring every nook and cranny cause that’s what I did. Even with all of that, I still didn’t hit the hundred hour mark on my first play through and I’m hitting even more stuff on the second play through and I’m 100% not gonna hit the 80 hour mark on this one. What gives?
