A.K.A.-47: To avoid cluttering the main page, here is a list of all fictionalized (or not) firearms in the game and their Real Life counterparts. Some of the names were changed to those of their real life counterparts in patches:
Thirty-Eight — Colt Police Positive
Brokk 17C — Glock 17C
Colt Anaconda — Colt Anaconda
McLusky .50 Caliber — IMI Desert Eagle
Braddock 9mm — MAC-10
Lassiter Killmatic — Uzi
Utica M37 — Ithaca 37
Jaegerspas XV — Franchi SPAS-15
Jaime Sue — Remington Model 700
Steyr Aug — Steyr AUG
Accidentally Correct Writing: Meta-example. In the French version of the game, there is a typo in one of Therese Voerman's lines (when you spoke to her after the "Slashterpiece" quest), in which there is written "Therese" where she would be logically speaking of Jeanette. Which actually makes sense. It could seem to be a clue unwillingly told (she was very upset at this moment, so she could have confused the names), foreshadowing the reveal that they are the same person, but it is actually really a mistake: the voice actress did say "Jeanette" and not "Therese".
Actor Allusion: When you get the briefcase for Fat Larry, he examines its contents and calls them "Beautiful." Larry is voiced by Phil Lamarr, who played Marvin in Pulp Fiction, and was connected to the briefcase arc of that movie.
Replay Value: Immense due to the fact playing a different faction of vampire changes the game noticable, with the Malkavian option nearly turning the entire game into a bizarro alternate universe. There are also numerous endgames possible depending who you ally with at the end.
