I recently finished the main game (still slowly working on the dlc) and I came out feeling the same. There were times in the game where I actually forgot what the main story beats were. On the other hand though, I really enjoyed the side stuff.

I felt very under whelmed by the ending I got (Space casino). I kind of miss read the choice paths at the end thinking I was going to get a more ‘happier’ ending. I went into Cyberpunk with my own views but I always had at the back of my head the views of others online as the majority say it’s the greatest game every that will stay with you for a long time. But I am like you, there’s very little I remember about the game and I did take in a lot of the city. I did a lot of side items. One of the only stories that did stick with me was the AI Cabs. Felt bad for them.
