New Vegas is the third worst fallout game out there.
Partially thanks to Avellone's SI, but also because holy shit there is literally no nuance to any of the characters except the NCR, and even with the NCR the nuance is only there to justify the independent ending being an option (it's fucking not, for the record, the mojave will fall apart without a strong guiding force and that leads to death). Every other faction that doesn't outright ally underneath you is evil. House? Evil. Legion? Stupendously evil. BoS? Evil until you effectively take over.
Only one of the DLC is any good, and that one is a parody!
