I'm not trying to start any pointless fan-fic between NV and L.A. Noire, but does New Vegas not seem like the perfect place for a Noire themed murder mystery? Somebody tell me i'm not the first to think of this.
Yeah, something like L.A. Confidential would do wonders, especially because interrogating suspects and collecting evidence could be done well. There were plenty of investigation elements in the casinos though.
Some film noir aspects would at least be great for a DLC. They could've done something like that with Point Lookout. Maybe it's also possible with Lonesome Road, assuming it has the drama it could have.
If it ever happens it'll be on pc consoles just arn't designed for those kinds of mods only a game that's intended as that. Tho I would love to see that it'd be very interesing to say the least.
