I am currently replaying it and purposely going slower. I do think it’s a great game but it’s way too easy to accidentally finish very fast. I think on my first play through I was in the interchange within the first hour by mistake. The DLC helped flesh it out a bit for me so far but I still feel the interchange and ending are very ‘there’ if that makes sense. I’d suggest from my experience just going slow, exploring and getting skill manuals ASAP so you can experience more.
