Honestly, there are a lot of internal references in the games, so it might make it less enjoyable, or just missing things.
Despite that, and the second title having references to the first one, I would suggest the second game, as it isn’t as cruel as the first. The first one requires a walkthrough or to be very patient and a fan.
Noir is more disconnected(I have only read 2 books) , but has a lot more witty and good dialogue compared maybe to the first two.
