New Vegas is better in every way
This is the first time I’ve read this on the entire internet.
I thought it was a pretty popular sentiment.
The RPG elements are expanded on massively, with multiple factions you can join and multiple endings. The characters are much more interesting. The gun mechanics are improved on with new ammo types and ironsights. The only thing I think Fallout 3 did better is the map, the map in New Vegas is pretty empty, though that’s kinda expected from the Mojave desert.
