I'm sorry, but graphics are a pretty bad reason not to recommend a game. As for the interface, certainly, it can be hard to work with, but frankly there are 'modern' games that control worse. For what it was and at the time it was being made, the controls and interfaces were awesome.

As for the references and toilet humor, that's part of what made the game, was that it didn't try to take itself too seriously. It was a game, and it didn't try to be some fantastic piece of art or some hugely epic story. And yet it's a game that's still fantastic for it's world.

True there are those that argue that the references pull it out of the original feeling of the fifties being unchanged, but at the same time, it makes it different from it's predecessor, and yet at the same time, something more.

Now, considering that, Fallout 3 is a direct successor to Fallout 1, while New Vegas is a more direct successor to Fallout 2. One is a survival RPG, and the other is an Action RPG.
