Wow you have a terrible opinion of games. Some people consider Fallout 3 to be the best game ever created not to mention all the awards it got.
Really? Then please add me to your list too!
Fallout 3 was not bad, but from my RPG point of view it was terrible. The only redeeming aspects were exploration and boatload of kick-ass mods.
And even that wont erase the terrible writing.
FNV wins for me in terms of story, dialogue, interactive enviroment(many of my actions impact the world around me), fleshed out characters and immersion overall.
The only weak spots I see are the bugs(which can be patched), and lack of exploration. And even that is debatable.
