Fallout 3 in my opinion is better but new vegas isn't bad at all, honestly I like 3 better mainly because of the fact it has a better story but as someone said below the gameplay in new vegas is better, also I think the dlcs are better as well. The only real good fallout 3 dlc was the hillbilly one! But I still recommend both, especially now with steam sales can get both with all the dlcs for like $25 GL And have fun!
