Such good memories of NOLF as a kid (both watching my dad playing them and trying myself for a short while).
My suggestions: LA Noire (with more adventure gamey-ness / improved mechanics, but essentially a lovingly crafted exploitable noir environment in that ilk). Grim Fandango (no idea how this would work but essentially I just want to walk around Rubacava again).
Basically, gaming needs more noir. It’s an untapped resource, pal.
