I did a book collection run once. Collect as many unique books as possible in a single run. I got about 94% of the books in the game, which is as many as I think you can get in a single run. The remaining 6% is locked behind story branches that would eat into the 94% I did get.

And honestly? It wasn’t that fun. I had to scour rooftops, look around in vases, cross-reference the wiki, reload the game because I made a wrong choice that seemed like a nothing choice at the time… And all I got were some notes. And they weren’t even much better than the ones you get in a normal run.

You can’t get 100%. You might be able to get 95%, but it won’t be fun. From now on, I’ll just clear the map markers before moving on, and that’ll be enough for me.

You’re right, I think I’ll just play more casually. Do you have any links or recommendations so I don’t miss anything important? The only thing I know is that I can’t let the fire burn forever in Scene 1."
