This isn't just one of the best Fallout games of all time, it's one of the best video games of all time, bar none. Mods are not necessary, but they are highly recommended. As with Skyrim, there are some mods for this game that add completely new questlines that meet or even exceed the quality of the baseline game. Seriously, whenever you get this game, check out the Someguy series by someguy2000 on Nexus. Autumn Leaves is also excellent.

You may also want to install certain performance mods to patch certain bugs and to help your game run better. Crashes are not frequent enough to be too bad, but the more mods you add, the more unstable the game may be. On top of that, there are also graphical mods, because, let's be real, the game is over ten years old and certainly shows it's age at times (not that it looked all that stunning on release!)

The DLC are all excellent as well.
The Ultimate bundle regularly goes on sale for 3-6 bucks, you really can't get better value than that, and, on sale or not, I recommend buying the Ultimate bundle.
