Better towns - also more believable, with water supplies, farms and hunting grounds.

There are 5 possible endings with hundreds of variations, if you count the DLC.

Weaker storyline, but better choices: 4 major factions you can side with, and you can destroy them all if you want to.

It continues the classic Fallout games and it's more of a apocalyptic western than pure post-apocalypse.

Worse atmosphere: New Vegas is post-fallout-post-apocalyptic, taking its inspiration from late 1970's movies such as “A Boy and His Dog” and “Mad Max”.

Fallout 3 loses the morality contest because it goes for the black&white approach, where you gather the forces of all that is good and beat the sh!t out of all that is evil.

Fresh combat system, excellent weapons, especially after the 'Operation Anchorage' add-on.

Megaton (built around a dormant, radiation-leaking, nuclear bomb), Little Lamplight ( built near a nest of insanely strong super mutants). You can't even join the Enclave for crying out loud! Or destroy BOTH the Enclave and Brotherhood of Steel. Fewer choices, Fallout 3 being too restrictive.Yeah, I know you can do it if you have the “Broken Steel” add-on, but since Fallout is an RPG with emphasis on choices, this option should have been in the main game! Powerful storyline - well except the ending where I don't understand why can't I send my radiation-immune friends to activate the purifier? It's an easy job for them after all and everybody can walk out happy.Better atmosphere: Fallout 3 is modern post-apocalyptic and feels like “The Book of Eli” & “Oblivion”.
