The first game was amazing. This game doesn't depart from the great formula the first game established but did fix several issues (such as giving more options for faster traversal of the map other than just fast travel and forcing less "sneak around and don't get caught" quests on you.)
All around, for me, this is one of the best console games of my life. It is #2 behind Elden Ring as my favorite game of the last decade.
If you loved SM1, you will love 2. If you haven't played 1 but enjoyed the Batman Arkham Asylum series this might also be a game for you.
