Similar experience here. The game is very impressive and immersive.

I was halfway in ACT II only to realize that I haven’t even met with Gale (a companion that you can recruit). I went back to do the Gale’s quest recently and discovered what practically counted for me as 10 hours of new content in ACT I.

Now, I think I concluded the story lines of ACT I and can move back to ACT II.

One could say it’s maddening to see this game sold for 70$…

You got a chuckle out of me. Thanks!
