Should I gat Fallout 3 GOTY?

I already beat the game and did all the original missions and I traded in my copy a little while ago.

I was just wondering if I should re buy it and play all the dlc because I didn't buy any of the add ons.

Are the dlc's good enough to go buy it again or should I just wait for a better game to come out?

Thanks. :)

If you really have a craving for more. If you don't want to play the story again I wouldn't get it
